load_image() function is stuck and cannot continue

muaxi8 — Wed, 26 May 2021 08:35:08 GMT

my custom board is LX2080。But it executes until the “”load_image“” function and cannot continue.

What is the reason?

Please refer to the following TF-A BL2 boot flow

a. BL2 initializes the DRAM, configures TZASC
b. BL2 loads BL31, BL32, and BL33 images to the DDR memory after validating these images BL31, BL32, and BL33 images form FIP image, fip.bin.
c. Post validation of all the components of the FIP image, BL2 passes execution control to the EL3 runtime firmware image named as “BL31".

Because there is problem at DDR controller initialization, so it is impossible to load BL31, BL32, and BL33 images to the DDR memory.

My custom board now uses the first DDR controller. Does the software need to be modified?

Could you please send me a fip_ddr.bin file, I suspect there is something wrong with my fip_ddr.bin

If you use different type DDR from the demo board, you need to modify DDR controller configuration.
