TDA4VM: Supported UFS device list

TDA4VM: Not able to flash descriptor to Micron UFS device

Hi TI,

we are using a Micron UFS device (MTFC32GASAONS) on a custom board. The board boots to Linux (using PSDKL v07.03) with the following UFS related messages:

root@j7-evm:~# dmesg | grep ufs

Reading the current configuration of the UFS device shows the following output:

Config Descriptor was written into config_desc_data_ind_0 file

So I would say, up to this point, everything looks fine.

However, when trying to flash the descriptor with the config TI provided (Creating a Boot partition with 32MB and a second partition with 32GB, which should fit in our device)

Trying to decrease the partition size like this:

According to this thread (https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1250436/tda4vm-supported-ufs-device-list), you only verified the Toshiba UFS device. Is Micron UFS device supported at all for TDA4?

Thanks for your help and best regards,

Felix
