Hi All,i am using stmp157 customize board, with linux yocto build system, and using USART1 configure as a hardware flow control RS 232, and RTO interrupt. and what i found is that CTSIF is not toggling and the proper status are not getting update on ...
i have download prebuild image en.flash-stm32mp1-openstlinux-6-1-yocto-mickledore-mp1-v23-06-21.tar.gzit working fine on my stm32mp135f-dk EVK. i want to add docker in it so need the build process of yocto image.Kindly guide me how to do it.
Hello,I want to persist data in flash memory from the Cortex M4 program.I created a section in the linker file:.mySection 0x000000001002f000 : { KEEP(*(.mySection)) } >RAM1_dataSo i know where my data is in the RAM memory but i don't know how to ...
I have an stm32mp153aab board with two sd card connections, they are identical except obviously one is connected to sdmmc1 pins and one to sdmmc2 pins. I have checked schematics and pinmux and everything looks good. sdmmc1 comes up in both uboot an...
I am trying to set up 3 ADC. I set PA4 to ADC1_INP18, PA5 to ADC2_INP19 and PF11 to ADC1_INP2. Will this be something that works? I am monitoring 3 lines (none NEED to be fast).I'm not clear on how to set this up. I am multiplexing several inputs...

Hi,I consider the boot option for our device. Normally we boot from qSPI EEPROM. STM32MP157 has an option to boot from SLC NAND. Does SLC NAND at STM32P157 have advantages in terms of read/write speed over qSPI? Thank you in advance!
This is a thread for your input how ST could improve providing known issues for example1. Update the WIKI2. Separate WIKI page,like this used on ST's Chinese website ?https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Visual_troubleshooting_gridhttps:/...
We plan to design a stm32mp13x board equipped with 8MB psram using FMC interface as system RAM. It's going to be very slow but that's fine for our application, and standby power consumption is the topmost priority in this project. How should we deal ...
Please show me a working example of setting up the MMU for STM32MP157D-EV1. and where to place the Translation table correctly (for cortex A7)It is assumed that all data and program will be located in DDR memory, without using the OS
