Dear Team, I recently brought STM32MP257-DK. I am able to explore the A35 part. Also I am able to run the example projects provided by ST for M33 core. Since My application will have more dependencies on the Realtime and hence I wanted to create a se...
Hi,I'm trying to run the whole ST-Linux-stuff on one core only to have the other one available for a time-consuming application. However, it seems the kernel-parameter isolcpus is not used, dmesg gives an output[ 0.000000] Kernel command line: roo...

Hi,when the STM32MP257F cores are running a regular Linux: how can I start some code on the M33 core? Is there a device/interface available within Linux that allows to send some code to this core and execute it? Or do they share some memory? So how i...
Hi,the TRM of the STM32MP257F describes different possibilities to boot the controller including the possibility to boot from eMMC or SD-card. And when looking to the EV-board, there are DIP-switches to choose eMMC or SD-card as boot-device too.But ...
Hi,I wanted to disable JTAG from production board by fusing OTP permantantly.I am trying with BSEC registers & OTP mapping. I am unable to write to any BSEC registers & doesn't change any value from uboot.Also tried with fuse but still same results. ...
