AM6421: am6421 EMMC

Please expect delayed response on your question due to our domain expert is out of office this week.

Hi Hong,

     Can you update in the issue posted above.

Thank You.

Hi Narasimha,

Right after Linux is booted, what is the output of the following command?

# dmesg | grep mmc0

Hi Bin Liu,

      The issue is we are not able to extract the root filesystem image to eMMC on custom board.

      i.e when untar is executed we get the error as attached earlier log.

      so, we cannot run the command  dmesg | grep mmc0, because we are not able to come up to Linux command prompt.

       The same sd card we are able to extract on AM64X EVM board. And we are able to boot from eMMC.

        Please suggest to solve this issue.

Thank you.

Hi Narashimha,

Please run this command in SD card boot before extracting the rootfs image to eMMC. You should have Linux prompt in SD card boot mode.

Hi Bin,

Please find below log.

Hi Sonu,

What is the DDR memory size on your board?

Hi Bin,

Please find below logs

Hi Sonu,

Does you board have 2GB DDR? It is printed in U-Boot boot log as "DRAM: ...".

Hi Bin,

Hi Sonu,

Please boot the board from SD card, and run the following command, let me know if it reports any error.

# memtester 1G 1

Hi Bin,

As suggested by you i got below logs after running "memtester 1G 1"

Hi Bin Liu,

  Thank you for the reply.

  Below is the part no for DDR on our board   

   K4A8G165WB-BCRC.

     Please advise if it is the issue.

Thank You.

Hi Narasimha,

Instead of 1GB, if you run memtester with a smaller memory size, for example 512M or 256M, or event 1M, does the same crash still happen?

Hi Bin,

Below is the log when i run memtester with 512M

root@am64xx-evm:~# memtester 512M 1
memtester version 4.5.1 (64-bit)

pagesize is 4096
pagesizemask is 0xfffffffffffff000
want 512MB (536870912 bytes)
got 512MB (536870912 bytes), trying mlock ...locked.

Done.

But when i extract "tisdk-default-image-am64xx-evm.tar.xz" i get same error below is the log.
