Programming eMMC via JTAG

rsk_11 — Thu, 02 Dec 2021 06:54:03 GMT

I am using iMX8QXP.

My query is can we flash the binaries( SECO,SCU,UBOOT,M4 APP,AP LINUX etc)
on the target board eMMC using JTAG?

We donot have SDCard or USB connection, hence is programming of eMMC via JTAG is possible?

Kindly provide any links or documents for help if any.

Thanks!

you can use trace32 to download scfw to the board, then use uboot to download images, see the attached readme

Thankyou for the reply.

The readme has steps for loading ATF and Uboot. Please find following queries for the same:

1. How to load a SCU FW scm_tcm.bin ?

2. Does the given .cmm script load the ATF and Uboot in given example to eMMC on MEK for iMX8QXP?

3. On our custom board we are using a different eMMC than the one used on MEK, How to generate .cmm for a different eMMC?

Regards.
