Resolved! PLL Calculation on STM32MP157A does not make sense.
I am working on the STM32MP157A. Setting PLL in the STM32CubeIDE does not work as expected. 24 MHz HSE DIVM4 = /5 DIVN4 = X84 DIVQ4 = /5 should = 80,460,000 . The MX program says 80,960,039. I do not understand. If the MX program is right, then what ...

Create a 32b parallel bus
Hello, I am working on the stm32mp157-dk1. I would like to create a 32bits parallel bus on cortex A7, at a frequency greater than 20Mhz but when I do a test on a pin I get a max frequency of 120khz, which is too low. I think this is the wrong program...
Understanding the functions of Remoteproc
Hi,iam a bit confused aboute the remoteproc framework and if my understanding of it is correct.In my view, the remoteproc framework can start the m3 firmware with having its elf-file in a dedicated place of the filesystem. The remoteproc also parses ...
