SK-AM62B-P1: how to setup the board using sd card.

Hi Suvendu,

I am routing your query to our MMC expert for comments.

ok 

Is it due to the MMC corruption? Why is it not working with the SD card anymore?

It is possible. If you re-flash the Linux image to the SD card, can the SD card boot the EVM successfully?

I tried re flashing the sd card it's not booting anymore.

I tried booting in UART boot mode there in serial it's printing only C

Can you tell me how to boot through UART using the command prompt and what to do after I get "c" in the lowest com port?

I am using a window system which documentation should I follow.

It's working now, I tried the UART boot mode and sent all three files mentioned in the link below using XMODEM and YMODEM file transfer using teraterm.

That's good!!

I believe you still want to boot from the SD card. If yes, could you please share the output of the following commands run from the A53 U-Boot?

=> mmc dev 1
=> mmc part
=> ls mmc 1:1

ya sure.let me try this

=> mmc dev 1
switch to partitions #0, OK
mmc1 is current device

=> mmc part

Partition Map for MMC device 1 -- Partition Type: DOS

Part Start Sector Num Sectors UUID Type
=> ls mmc 1:1
** Invalid partition 1 **
Couldn't find partition mmc 1:1
=>

can I reconfigure the EVM with my Windows system to boot the EVM from sd card or eMMC?

There are no images in the SD card so the boot expectedly fails. Please reflash your SD card and try booting again.

Hit any key to stop autoboot: 0
=> mmc dev 1
switch to partitions #0, OK
mmc1 is current device

4 file(s), 1 dir(s)

Now the images are there so you should be able to boot from the SD card. If you are still not able to boot, please share the snapshot of the board configured to boot from the SD card.

Still, it is not booting from the SD card.

Can you once share the hex string that appears on the UART console in the UART bootmode?

02000000011a0000616d3632780000000000000048534653010001000100010002a6000000000000d68ecb2c055dff11ade95bd927e837d2a53bc23b0a2800cebce4f106bcf309df2213912d77a157a8b7c2df40672a06a918034aa4c7d603e462481475225d49b8ad0bc40b000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000b94b017bd4fb09f8d956714c0183e2cde450a879ca22c0ccd7166d6e032be445C

Okay. The device type is HSFS so the SD card flashed with the default WIC image should boot successfully.

Can you please share the full snapshot here?

Yes, now it's booting from the SD card successfully.

Thanks a lot.
