Unable to program the eMMC using STM32CubeProgramer with a signed & encrypted arm trusted firmware and FIP

[ThinhNguyen]

Hardware setup:
- STM32MP257F-DK

- The OTP in the chip is burned with the correct OTP value and it is closed.

- Connect CN15 USB Port to a Ubuntu Laptop.

- BOOT0 = BOOT1 = BOOT2 = BOOT3 = 0

- Power on the DEV KIT.

Software:

Program the DEV KIT via USB Using STM32CubeIDE
At first, STM32CubeProgrammer can connect to the DK via USB. After that, The DEV KIT keeps disconnected after loading arm-trusted-firmware and fip. Below is the log from STM32CubeProgramer.

From the log, I found that the arm-trusted-firmware and fip are downloaded. Afterthat, The board die. I am sure that my OTP and device closing are correct because the board can boot from SD card with Signed and Encryted boot loader. Please help with this issue.

I seems the process is done successfully. It may not delete all eMMC, just nesesary sectors.
