TDA4VM: Problems with getting access to UFS interface

felix_123

Part Number: TDA4VM

Hi,

I am currently trying to execute the instructions given from this thread e2e.ti.com/.../922975 to mount UFS in Linux. I am using the PSDKLA

07_00_01 and I updated to SD card boot files according to the Getting Started Guide of the PSDKLA to u-boot version 2020.01. However I get some strange output when booting up and additionally, when I try to execute step 3) and 5) of the already mentioned thread from the beginning.

After the kernel has been started, I get this output when executing step 3) from the thread:

root@j7-evm:~# ufs-utils desc -t 1 -w ./config_desc_data_ind_-p /dev/bsg/ufs-bsg0

 Err: Missing device path type

And for step 5) at the u-boot prompt, I get this error:

=> ufs init
ti_sci_power_domain_on: get_device(277) failed (-19)

What is missing in my configuration so that I can execute these commands properly? Sorry if the solution is obvious, but I am new at working with the TDA4 board.

Thank You!

Hi,

U-Boot SPL 2020.01-dirty So something is dirty(changed) can you prepare the card using bin/mksdboot.sh script?
So that we use the pre-built images.

Are you using a custom board or its a TDA standard TI EVM?

Best Regards,
Keerthy

Hi,

this partly solved my issue. I get now this output when booting:

But I still have problems with executing the ufs-utils command. I copied config_desc_data_ind_0 to the rootfs partation of the SD card to rootfs/home/root. (There were problems with the copy command so I executed it in sudo mode)

cp config_desc_data_ind_0 /media/USER/rootfs/home/root/
cp: cannot stat '/media/USER/rootfs/home/root/config_desc_data_ind_0': Permission denied

After this, I booted and tried to execute the ufs-utils command in kernel prompt. But I get again this as an output:

root@j7-evm:~# ufs-utils desc -t 1 -w ./config_desc_data_ind_-p /dev/bsg/ufs-bsg0

 Err: Missing device path type

When executing the commands in the u-boot prompt, I get this as an output:

ufs init
Device at ufs@4e84000 up at:[RX, TX]: gear=[3, 3], lane[2, 2], pwr[FAST MODE, FAST MODE], rate = 2
=> scsi scan
scanning bus for devices...
=>

So I do not find any relevant devices. So maybe there went something wrong with copying the config file?

cp config_desc_data_ind_0 /media/USER/rootfs/home/root/

cp: cannot stat '/media/USER/rootfs/home/root/config_desc_data_ind_0': Permission denied

After this, I booted and tried to execute the ufs-utils command in kernel prompt. But I get again this as an output:

Your copy has failed. Please use sudo to copy to your file system and try. This should work.

If it works please resolve.

Hi Keerthy,

yes you are right. But the original problem was instead, that, when booting the TDA4 with a LAN cable plugged in, it could not find the correct copied config file. Unplugging and afterwards executing the ./setup.sh solved this issue. Thanks again.
