Hey I found a strange documentation on your wiki pagehttps://wiki.st.com/stm32mpu/wiki/STM32MP15_OTP_mapping 3: 14-7 (8 bits)UART instances disablingIf it is different from zero, then each bit disables an UART instance.Collapse0b00000001: reserved0b0...
I guess there is a typo on the following page (and i couldn't find the proper place to report that)wiki.st.com/stm32mpu/wiki/SPI_device_tree_configuration"Both /delete-property/dma-names and /delete-property/dma have to be inserted to get rid of DMAs...
What does the OTP 9 Bit 0 do?There is nothing in the ref manual.
What does the OTP 3 Bit 15 do?Can I disable the boot cache for more security? Or does it have more impact on the system?
The flashing process of our STM32MP1 SoM is very slow, it took about 3 and 1/2 hours to flash to whole 8GB eMMC. We use the STM32_Programmer_CLI and have a usb connection which shows up in DFU mode. How can we speed up the flashing process? How coul...
I've written a script that basically builds everything based on this wiki - wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#Updating_the_kernel_device_treeWith the script I can successfully build from the existing ...
Hi,how to compile fsbl to test ddr3 purposes. Unfortunately, I can't use the official one due to different UART4 debug pins and I2C4 PMIC. I can't find a good link with simple instructions. Maybe someone gives me a link or short instructions on how t...
I have to read ADC readings from 4 channels on both ADC1 and ADC2. In production mode, when OPENAMP isn't enabled, everything works as expected; however, when it's enabled, two channels are getting garbage readings. I do not know why or how to fix it...
Hello,We are working on stm32mp157A processor.we are using uboot-2021-10 version, while booting we are getting invalid MAC address. as in below image.we tried to set the MAC address by using following commandssetenv .flags ethaddrsetenv ethaddr 11:2...
Hi,When I power on my STM32MP157A-DK1 board, ST-LINK LED (LD4) is always red. On my Linux system when I connect the board through ST-LINK micro usb port (CN11), it is only detected as 'STM32 Virtual ComPort', and not detected as StLink device. And wh...
