TDA4VM: Uniflash - TDA4VM

Hi,

I would like to flash the uboot into eMMC, without using SD-Card, and with the help of Uniflash tool.

I have gone through the user manual given here https://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#getting-started-with-uniflash

I have below doubts:

1.) Do I need to partition the eMMC before writing the Uboot?

2.) Can I use the command like below?

#sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f /home/user/ti/uniflash_6.0.0/processors/FlashWriter/J721e_evm/u-boot.img -d 4 -o 0

Can the flash programmer take care of the partitioning?

Thanks and Regards,

Karunakar

Hi Karunakar,

eMMC flash support as part of Uniflash is limited to raw data write to eMMC boot partition. We don’t have support for writing the data as a file to user area.

If you have OSPI on your board, then you can flash the u-boot to the OSPI and then use u-boot to write into the eMMC?

Hi Karthik,

Thanks for the reply.

can we write the uboot into eMMC in raw data write?

Is there any size limitation or any problems in this approach?

Thanks and Regards,

Karunakar

HI Karunakar,

I was mostly thinking about UART boot of the u-boot to keep it simple and then write to the eMMC.
