Resolved! How to program OTP on STM32MP1
I followed ST wiki, success to display OTP by the command:STM32_Programmer_CLI.exe --connect port=usb1 -otp displThen I try to test writing a value to wordid 79 which currently is 0x00000000, and free for user.STM32_Programmer_CLI -c port=usb1 -otp p...

Resolved! Urgent: Cannot boot from NAND - OTP
Problem: After configuring the OTP pins in word 3 to the following:- Primary boot source : SD-card- Secondary boot source : FMC NANDAnd flashing the FMC nand with TF-A `tfa-*-nand.stm32` in the first sector using `nandwrite -p /dev/mtd0 /mnt/boot/tf-...
Resolved! FIP Secure Boot Can't Find Key
I've followed this walkthrough perfectly: https://wiki.st.com/stm32mpu/wiki/How_to_perform_Secure_Boot_from_Distribution_package#Distribution_package_with_signed_FIPand I get a "Not able to find "None" (socname stm32mp15) path from current BBPATH var...
I am using STM32MP157F-EV1. I want to enable the CM4 SWO output on the SWO debug pin. Is there any code example or sequence to accomplish this? It is a bit more complicated since this is an MPU target and you have to select between the A7 and the M4.
I am currently running in Engineering mode. In this application I am not using Linux on the A7, so I want to enable the trace SWO output from the M4 processor.
Resolved! Inaccurate measurement of VREFINT
Hi everyone!I see unexpected values when measuring VREFINT. The ADC measures around 1.18V, on some boards even 1.16V, which is outside the tolerance according to the datasheet: Reading the calibration value VREFIN_CAL from OTP memory returns a value ...
TRGO not triggering ADC DMA conversion in STM32MP1 Cortex-M4
Hello,I'm trying to trigger a conversion in a frequency of 4700 HZ. To do so I used cubeMX to configure the ADC to work at DMA circular mode and to be triggered by TIM4 trigger out event on the rising edge. I made sure to activate DMA in high priorit...
How to protect Bootloader binary on STM32MP15xxx
Hi,We see signing + encryption bootloader on STM32MP13xx,But on STM32MP15xx, there is only signing. The raw binary still start from offset 256 of the signed file. This only make sure the board doesn't run a strange bootloader, but doesn't prevent som...
