STM32MP1 & ThreadX RTOS
Hi, during Embedded World I got MP135F devkit. I'm not into Yocto, but guy from ST told me, that MP1 can be used with RTOS but with halved max frequency. I have experiance with ThreadX on H735.Can you hint me how to start? Are there any tutorials? I ...
Integrating STPMIC1 with STM32MP131F over I2C
I am adding the STPMIC1 on our custom board.While configuring device tree, when we are using scmi, how should device tree configuration look like? Should we still need to add i2c4 node? Or just adding scmi_regu entry will be enough?Regards,S
STM32MP157F-DK2 + Arduino Ethernet Shield + w5100-spi.c linux driver
I am attempting to implement a second ethernet interface on STM32MP157F-DK2 by using the Arduino Ethernet Shield, which is based on the Wiznet W5500 chip. The implementation aims to use SPI assigned to A7 core to communicate with the shield, which wi...
Can't Access Some DDR Locations (STM32MP157F-DK2)
Hello,We are currently working with the STM32MP157F-DK2 board and the on-board SDRAM (DDR3L). The memory map says that region (0xC000000-0xDFFFFFFF) is for the DDR system, however when we try to write to some of the memory locations inside this range...
Resolved! STM32MP1: SPI transfer has delay every eight bytes
Hi, on SPI, does anyone know why every 8 bytes then it has a big gap?We tried:1MH, no gap,2MH, gap occurs,4MHz gap bigger,8MH gap bigger than 4MHzSeem higher frequency, bigger gap We don't use DMA
Resolved! Unable to find the partition with the uuid mentioned in metadata
Hello everyone,we have developed a custom board based on stm32mp157 chip. We also forked the tf-a and u-boot from meta-st layer. If we flash an sd card using the flash layout, image works. But my goal is to copy the files from linux host machine, whi...
