Hello,
My customer face following issue.
* When they transmit data from SD card to eMMC, they observed attached error message(SD_eMMC_issue.txt).
However, case of writing data to eMMC not from SD and case of reading data from SD not to eMMC can be worked.(mmc_write2.txt(write to eMMC) and SD_read.txt(read from SD))
They use SDK ver 8_05_00_21 and it seems this issue is similar to following thread.
(+) PROCESSOR-SDK-AM62X: AM625 eMMC stablity issue - Processors forum - Processors - TI E2E support forums
If you have any idea to avoid this issue, could you please tell me about it ?
BR,
