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...
Hi,My test kit is STM32MP157C-DK2, the image is "st-example-image-qtwayland", the display is DSI display.I tested with procedure:1. run " /usr/share/examples/gui/analogclock/analogclock"get error message:"root@stm32mp1:~# /usr/share/examples/gui/anal...
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-...
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 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.
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 ...
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...
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...
I need giga ethernet working on linux.Is it possible with the STM32MP?Please let me know if you have any test results with iperf.Thank you for answers.
From instructions, I opened two console: Console 1: openocd -f board/stm32mp15x_dk2.cfg This looks good as output: ``` ... Info : stm32mp15x.cm4: Cortex-M4 r0p1 processor detected Info : stm32mp15x.cm4: target has 6 breakpoints, 4 watchpoints Info ...
