Hello,

I'm using a custom board with a single QSPI S25FL512S on SPIBSC0 with 32 MB of external SDRAM.

I would like to boot a non-XIP kernel with a writeable UBI or EXT3 File system.

Unfortunately, I cannot boot my system...

I've enabled CONFIG_SPI_SH_SPIBSC and I'm using the SAME spibsc params as the RSKRZA1 board.

Am I missing something ?

Here's my bootlog :

Hi,

I am using three RZ/G1M starter kit boards to run three different AI application. I am using OpenCV to display the video output from each of those application to a single HDMI Monitor through a HDMI switch.

When I am switching to different HDMI out using the HDMI switch i am not getting the video out on my HDMI monitor and i am not getting any error from OpenCV also, and when i restart the weston using /etc/init,d/weston restart it continuous the video streaming from my application.

So i have to restart weston whenever i switch to a new HDMI out using HDMI switch.

I am using yocto-1.6

Is there anyway to configure weston to restart weston automatically when there is new HDMI connection established or how to detect the switchover in HDMI out.

Regards,

Gopi

Hi,

I need to use the SCI(5) with a baudrate around 1MHz. The driver calculates this to a value of 2 for the bitrate register. This results in large deviations (up to 12%) for the actual baudrate. It seems the only way to get a more precise value is to lower the prediv value or increase the peripheral clock. Both seem pretty much unchangeable. (The driver already picks the lowest prediv value).

Are there any other options?

Thanks!

Kind regards,

Hello Renesas,

We are using RTC ds3234 connected through SPI interface (MSIOF1), facing
the below issue.

1. Chip Select is not toggling during data transfer.

Following are the settings done in dts:

&msiof1 {
         pinctrl-0 = <&msiof1_pins>;
         pinctrl-names = "default";
         status = "okay";
         rtc@1 {
                 compatible = "ds3234";
                 reg = <1>;
                 spi-max-frequency = <4000000>;
         };
};


    msiof1_pins: spi2 {
                 renesas,groups = "msiof1_clk_b", "msiof1_tx_b",
"msiof1_rx_b",
                                  "msiof1_ss2_b";
                 renesas,function = "msiof1";
    };

Working Environment :

Hello,

    We are trying to put board to suspend mode using "echo mem > /sys/power/state" command .

When i try wakeup using UART board hangs and i get below error:

Since i was getting i2c5 error i did below testing

Observation:

• i disabled i2c5 in dts it was working fine .
• If we remove IO Expansion connector without disabling i2c5 in dts Suspend wakeup is working fine.

Devices connected to i2c5 bus are:

• Main board:   HDMI, RTC(DS1307Z) 
• IO Expansion connector : Ambiant light sensor(OPT3001DNPT).

Hi,

I've updated to the latest linux 4.9 kernel.

When I now run `aplay -l` it shows:

**** List of PLAYBACK Hardware Devices ****
card 0: rskrza1max9856 [rskrza1-max9856], device 0: MAX9856 max9856-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So this looks nice, but whenI then run `aplay file.wav` I get:

scu playback route is invalid.
scux-pcm-audio scux-pcm-audio.0: ASoC: can't open platform scux-pcm-audio.0: -1
aplay: main:807: audio open error: Operation not permitted

It looks to me it has something to do with the Device Tree, but I did re-flash the dtb file.

Am I missing something?

Kind regards,

Remco Poelstra

Hi,

I am using RZ/G1M to run my application. When I am using yocto-2.0 the application is very slower(2 times)  when compared to running on yocto-1.6.

Is there any optimization i have to do since i am planning to use yocto - 2.0 which will resolve other problems..

Only difference i could find is gcc compiler version is different.

Yocto-1.6 - gcc-4.8

Yocto-2.0 - gcc-5.2

Thanks.

We are modifying an existing custom board built around a RZ/A1 and intend to add a LAN9514 for Ethernet functionality.

Has anyone tried this?  Any hints or sample code would be greatly appreciated.

Note: Our software environment is built around CMSIS RTOS, not Linux - if that matters.

Thanks.

Hi,

I'm using a Laird Sterling-LWB module for bluetooth. It uses an HCI4 interface, which I've wired to SCIF5 on the CN44 connector. In my DTS I've made an alias to serialport 1:

aliases {

  serial0 = &scif2;

  serial1 = &scif5;

}

I've also configured the pins like:

scif5_pins: serial5 {

  pinmux = <RZA1_PINMUX(11, 10, 3)>, /*TXD*/

                 <RZA1_PINMUX(11, 11, 3)>, /*RXD*/

                  <RZA1_PINMUX(11, 7, 3)>, /*CTS*/

                  <RZA1_PINMUX(11, 8, 3)>; /*RTS*/

 }

And enabled the port:

&scif5 {

  pinctrl-names = "default";

  pinctrl-0 = <&scif5_pins>;

  status = "okay";

}

I run at a baudrate of 1041406 (the SCIF believes that it runs at 1152000, but this is the closest it can get). I've checked the incoming and outgoing baudrates and they are near perfect.

Unfortunately I get a lot of overrun errors when larger packets are received. I never see the CTS or RTS lines toggle though.

Did I miss something about getting the RTS and CTS lines to work? I would expect the RTS line to go high when the FIFO is (almost) full. (I checked that flow control is requested using termios.c_cflag).

Another question is why can't the ARM keep up with an UART running at 1MHz?

Thanks in advance.

Kind regards,

Remco Poelstra

I'm trying to get familiar with the USB capabilities of the RZ/A1, so I'm trying the USB Host Sample2 from the RZ/A1 Framework (AN3639) on a RSK board.

The sample app compiles and seems to load into flash properly - but when I reset (or power cycle) the board, I see no activity on the debug serial port.

Anyone have experience with this app note?  I've successfully used the samples from the CMSIS-RTOS BSP app note, so I'm fairly sure my hardware and environment are functional.  And I've run the "Blinky" sample in RAM and it behaves as expected.  (Although I've not been able to get Blinky to run out of flash, either).

Thanks.

Hi all,

I am trying a scaling, displaying, and file saving on RZ/G1E (BSP for starter kit + multimedia package).
But, display image is wrong. I attached the image.

This is the flow of concrete processing.

  H.264 dec -> scaling & NV12 format convert with VSPM (DATA-A)
    DATA-A -> format convert with VSPM -> display(wayland)
    DATA-A -> NV12 file saving

[Command]
# gst-launch-1.0 filesrc location=input.mp4 ! qtdemux ! omxh264dec ! vspmfilter outbuf-alloc=true ! video/x-raw,format=NV12,width=800,height=480 ! tee tee0. ! vspmfilter outbuf-alloc=false ! video/x-raw,format=BGRA ! waylandsink sync=false async=false tee0. ! filesink location=output.dat sync=false async=false

BTW, if set I420 format, display image is good.

# gst-launch-1.0 filesrc location=input.mp4 ! qtdemux ! omxh264dec ! vspmfilter outbuf-alloc=true ! video/x-raw,format=I420,width=800,height=480 ! tee tee0. ! vspmfilter outbuf-alloc=false ! video/x-raw,format=BGRA ! waylandsink sync=false async=false tee0. ! filesink location=output.dat sync=false async=false

Do you know how to resolve?

Not sure if this is an RZ issue, but I thought I'd start here...

I'm experimenting with the USB Host Sample 2 from the RZ/A1 Framework V1.03 (app note R01AN3638EJ0103) on the RSK board.  It seems to work as expected with one of my USB thumb drives, but a different drive reports a Media Sector Size of 0 bytes (instead of the normal 512).  Both drives work OK on my Windows machine.

Also, with the "bad" drive plugged in, the call to ioif_read() doesn't return.

Does this sound familiar?  Smells like a bug in the Renesas USB driver code.

Thanks.

Hi all,

Hi,

We have Sgtl5000 audio codec interfaced with RZ/G1M processor.

If we play a audio file after the system wakes up from the suspend mode we get noise along with the audio.

But before putting the system to suspend mode audio is working fine(No noise).

Please let me know what is the issue. 

Hello,

We are using RZ/A1H platform 256 BGA package on our kit.

The common use of that controller in our project was for video processing, but now we should extended its features. Almost all of the peripheral pins of processor are used (8bit input and 16bit video output, 2 SD interface channels, SDRAM interface (16Mx16), and etc.), so we haven't so many options for alternative pins.

My question is:

Can we get the output video data (16bit) from channel 1 and get clock signals (PIXCLK, HS and VS) from channel 0?

There is information about "Output Controller" and "System Controller" in the User_Manual, but I could't find is this possible.

I would be glad for any response.

Regards,

Petar

Hi all,

We have a custom made RZA1L based board and using latest BSP-4.9, using MACRONIX-MX25L3233F (32Mb)  flash, made the appropriate changes as per our board,

Pins Used for console

pfc_set_pin_function(7, 1, ALT4, 0, 0); /* P3_0 = TxD2 */
        pfc_set_pin_function(1, 10, ALT3, 0, 0);        /* P3_2 = RxD2 */

AND  for SPI  We used

pfc_set_pin_function(4, 4, ALT2, 0, 0); /* P9_2 = SPBCLK_0 */
pfc_set_pin_function(4, 5, ALT2, 0, 0); /* P9_3 = SPBSSL_0 */
pfc_set_pin_function(4, 6, ALT2, 0, 1); /* P9_4 = SPBIO00_0 (bi dir) */
pfc_set_pin_function(4, 7, ALT2, 0, 1); /* P9_5 = SPBIO10_0 (bi dir) */
pfc_set_pin_function(4, 2, ALT2, 0, 1); /* P9_6 = SPBIO20_0 (bi dir) */
pfc_set_pin_function(4, 3, ALT2, 0, 1); /* P9_7 = SPBIO30_0 (bi dir) */

And follwed the  instruction as per porting guide.  and selected macronix driver , build u-boot and flashing the image into the spi flash using  below command.

./build.sh jlink output/u-boot-2017.05/u-boot.bin 0x18000000

able to flash the  u-boot into the flash.

But not able to see anything in serial port.

Tried to  build  and download to RAM  Boot directly by using mode=3 but still not getting any on console.

Please any one here guide me what am i missing here and how to go about it.

Thanks and regards,

Nagaraja

Hi,

I  have written an application on RZ/A1H starter kit+ which does play audio on speaker for FreeRTOS. I am using e2 studio for development and debugging.

Currently, Code runs fine for around 15-30 minutes when playing audio continuously after that prefetch handler gets called.

backtrace doesn't help here. It prints the prefetch handler location only.

Can you please guide me how to debug this issue?

Hi,

I have the RSK+RZT1 Board and want to use the SWV interface in order to redirect the printf() function output to the SWV interface. How can I do this? This is my first expirience with ARM CPU and SWV interface.

I've tried the IAR Embedded Workbench and setting the library stdout to SWO and enabling the Terminal I/O but without any results.

Hi All,

In the end of 2017 there was information that Renesas prepare Android BSP for RZ/G. Does anyone know readiness? Any possible to get it?
