PetaLinux 2016.4 U-Boot ZCU102 MMC write not working

Jump to solution

Hey,

 

I'm currently having a problem where I am unable to write more than two blocks to my MMC device at once. Reading any number of blocks from the MMC device as well as reading/writing from within the PetaLinux Kernel work fine though.

The MMC device has an EXT2 partition on it.

 

reading:

Hensoldt> mmc read 0x10000000 0 100

MMC read: dev # 0, block # 0, count 256 ... 256 blocks read: OK

writing:

Hensoldt> mmc write 0x10000000 0 100

MMC write: dev # 0, block # 0, count 256 ... sdhci_transfer_data: Error detected in status(0x208000)!
mmc write failed
0 blocks written: ERROR

Did anyone run into a similar problem? Thanks for your help!
