Hy i wanted to ask how i can set the clockspeed on my Device tree so the USART3 will work with 10MB/s my device tree looks at them moment like this:&usart3 { pinctrl-names = "default", "sleep", "idle"; pinctrl-0 = <&usart3_pins_b>; pinctrl-1 = <&usar...
Hi,While following the example at https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Package#Updating_the_kernel_device_tree, I'm running into problems downloading the SDK.The link provided from instructions below, al...
We are using SoM MYC-YA157C from MYIR with STM32MP1 onboard. MYIR creates pretty device-tree hierarchy, which is handy for update. CubeMX creates partial single device tree file. I would like to merge some of it parts (pinmxing, for instance) with ...
I used the latest official version（2021-03-31） to configure the stm32mp157c-dk2 of the optee version, and used the official tutorial to generate fip.bin and burn it to the corresponding partition, but it seems that the image is not checked,in other w...
Can I use STUSB1602 with STM32MP1?The STM32MP157C-DK2 has an STUSB1600, but it is not a PD controller, so I am reviewing the STUSB1602.STUSB1602 seems to support only STM32F0, STM32F4, STM32G, and STM32L.I'm curious to see if it is possible to port a...
Hi, I have tried to build the Distribution Package following this guide: https://wiki.st.com/stm32mpu/index.php/STM32MP1_Distribution_Package#Building_the_OpenSTLinux_distributionMy goal is to run a build that is as small as possible. Therefore I cho...
I'm working with the STM32MP157C-DK2 dev board and I've noticed that sometimes when powering up the board there is a 20-30 second delay where I don't even see the boot up messages. It's doesn't appear to be U-boot related either. Has anyone else not...
Hi, we are currently bring up our custom STM32MP157 Board. We get in any constellation a "DDR addr bus test: can't access memory @ 0xc000004"We think that our crystal is correctly running at 24 Mhz because we connecting over USB to the Board. Also th...
Openssl fails to convert the certificate from der to pem. Is this expected? I wrote a c program in OpenSSL to extract the public key, which seems to work, but I need to verify its correctness. Is there another tool like openssl that I can verify the ...
