In the Beal environment, what files are needed to generate FIP after compiling OP-TEE?

[ssw.1]

When I use sp_ min, I use the following command to generate fip in the Bareenvironment, and can start the u-boot normally:

fiptool create --tos-fw bl32.bin --nt-fw u-boot-nodtb.bin --fw-config stm32mp157d-***-fw-config.dtb --hw-config stm32mp157d-xx.dtb --tos-fw-config stm32mp157d-***-bl32.dtb fip.bin

But when I use OP-TEE, I use the following command:

fiptool create --tos-fw tee-header_v2.bin --tos-fw-extra1 tee-pager_v2.bin --tos-fw-extra2 tee-pageable_v2.bin --fw-config stm32mp157d-***-fw-config.dtb --nt-fw u-boot-nodtb.bin --hw-config u-boot.dtb --tos-fw-config stm32mp157d-***-optee.dtb fip.bin

 

The result is that can't enter the u-boot，stuck somewhere， I don't know whether there is a problem with the configured op-tee system or the generated fip method is wrong?

Please take a look.

Thank you very much.

Hi ssw.1 (Community Member)

Which OSTL distribution you use? Did you compile OPTEE with your board? Sounds like the TF-A FW_Config address doesn't match the one in OPTEE. Otherwise you need to enable DEBUG trace in OPTEE to see what's going on.

Thank you for your reply. I fixed the DDR size setting, but a new problem occurred later:

Is it because the power supply I use is fixed?

There is no PMIC on my board

Do you have a device tree file that uses an independent power supply as a reference

Hi ssw.1 (Community Member)

Did you enable the RNG in DT optee? All regulators (regulators-fixed) should also be in declared in OPTEE DT board

I don't have a DT file in discrete power supply configuration as reference. But some SOM maker partners have done so already on previous OSTL DV

@ssw.1Did you solve this? I'm having the same problem (minus the RNG not available message):

E/TC:0 0 probe_driver_node:413 Failed to probe stm32mp1-cpu-opp on node cpu0-opp-table: 0xffff0000
