Resolved! I've come across the chip ID caveat mentioned in the op-tee documentation for secure storage. Are unique chip IDs implemented in STs branch of the op-tee OS? Also is trustzone code itself stored securely at rest or only the data in secure storage? Thanks

Full text from op-tee: Important caveats Currently no OP-TEE platform is able to support retrieval of the Hardware Unique Key or Chip ID required for secure operation.   For all platforms, a constant key is used, resulting in no protection against de...

Hello, I am trying to execute a simple ADC program(12bit) in stm32mp157c using trimpot with 10K as input in cube ide. Where output changes only at the voltage level of 3.2v

While changing the value at the trimpot output values is constant(4095) and has no change as soon as when it reaches 3.2V it goes to zero. I am seeing output using uart. ​Please assist me how to rectify it.​

Resolved! I have been following the instructions on the wiki to set up STM32CubeProgrammer on dk2. It appears I am missing port parameters. What is the correct command line?

I enter STM32_Programmer_CLI -c port=/dev/bus/usb/010/003 (lsusb reports this is correct) -w flashlayout_st-image-weston/trusted/Flashlayout_sdcard_stm32mp157c-dk2-trusted.tsvudev drivers installed, Ubuntu 20.04Warning: Wrong connect parameter:

Resolved! I want to power the STM32MP157 card by the + 5V of the CN2 connector to integrate the card on a motherboard of a control system. The card does not boot if power is supplied from CN2.

Only the power supply via USB C CN6 allows booting with detection of the presence of voltage on GPIO PA5 and PA4. Is there a way to modify this control mode and be able to boot with a CN2 power supply? Is it possible to modify the FW so as not to re...
