Hello!
I have a problem with op-tee start on imx8mm_evk
(https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-for-the-i-mx-8m-mini-applications-processor:8MMINILPD4-EVK).
My .config file is attached.
I write output/images/sdcard.img on sdcadr, connect terminal emultaion with serial port and start imx8.
After below output imx8mm_evk is output nothing.

Problem arises after jump execution on op-tee entry point address (0xbe000000)
After reaching the above address breakpoint, we have content in memory:
(gdb) x/10i $pc
=> [34m0xbe000000[m <[33m_start[m>: .inst 0x00150000 ; undefined [34m0xbe000004[m <[33m_start[m+4>: .inst 0x00000000 ; undefined [34m0xbe000008[m <[33m_start[m+8>: .inst 0x00000000 ; undefined [34m0xbe00000c[m <[33m_start[m+12>: .inst 0x00000000 ; undefined [34m0xbe000010[m <[33m_start[m+16>: .inst 0x00000000 ; undefined [34m0xbe000014[m <[33m_start[m+20>: .inst 0x00000000 ; undefined [34m0xbe000018[m <[33m_start[m+24>: .inst 0x00000000 ; undefined [34m0xbe00001c[m <[33m_start[m+28>: .inst 0x00000000 ; undefined [34m0xbe000020[m <[33m_start[m+32>: .inst 0x00000000 ; undefined [34m0xbe000024[m <[33m_start[m+36>: .inst 0x00400000 ; undefined
As we look, it is not valid instructions opcode.
After continue execution, imx8 freezes.
Guess that the op-tee was not load in memory in uboot-spl.
