DRA821U: fatload mmc 1 0x80080000 qnx-ifs, I get mmc_init: -110, time 196

Hi,

Some general questions:

• Which TI SDK is under test?
• Do the contents of the SD card appear correct, when viewed from a host machine?
• Have you tried testing with a different SD card?   

Thanks,

kb

Can you share the full logs?

TI SDK used ----- 

ti-processor-sdk-qnx_j7200_08_01_00.tar.gz along with 3 patches(08_01_05)

ti-processor-sdk-rtos-j7200-evm-08_01_00_11

ti-processor-sdk-linux-j7200-evm-08_01_00_01

The U-boot is loaded from SD card only so the SPL is able to detect the SD card. But in U-boot it is not detecting SD card. I have tried with many SD cards. For formatting the SD card I have used the script given in the TI SDK.

Finally I loaded qnx-ifs from tftp. After that QNX is able to detect the SD card. However when I wanted to mount ext4 partition to /tmp it was not possible. I could mount fat partition to /tmp. 

Please suggest.

Thank you.

Hi Shrinivas,

I am able to successfully load images from SD card on my DRA821 EVM. My question is if this is a custom board or you are using a standard TI EVM?
Do you have a different EVM where you have SD functional in U-Boot?

- Keerthy

Hello Keerthy,

Sorry for the late reply.

I am using the standard TI board. I only have one board. Could you please let me know from where to take the u-boot. I have taken the u-boot from boot-j7200-evm.tar.gz from linux SDK. Version 20211221164112.

Thank you.

Hello Keerthy,

I still face the same issue. Since I am able to boot till u-boot, I think in SPL stage SD card is detected. Only in u-boot it is not detecting SD card is what I feel. 

Thank you.

Hi Shrinivas,

We have multiple boards that work fine & boot all the way till Linux kernel. Have you had a chance with different SD cards?
This is not a known issue. Hence the request.

- Keerthy

Hello Keerthy,

I have tried with 3 SD cards it is still not working. However I tried with another board from another team. There SD card boot is working. So not sure what is the problem.

Thank you.

Hi Shrinivas,

Can you add prints in the sdhci driver and let me know where exactly the failure -110 is coming from? I am not able to reproduce this on my board. So any details on the exact point of failure on your board will be really helpful.
