The issue I am having is BKPSRAM is not retaining the information I write to it after a power cycle. I can read and write to BKPSRAM after I set it to non-secure in optee, removed the power features in pwr_regulator, and I enabled the CLK bit. I have...
Hello,I am trying to use I2C2 peripheral with DMA2 streams 2 (Tx) and 3 (Rx). I am also using OpenAMP to communicate with A7 core, which runs Linux.A short time after launch, a Hard Fault is triggered. I noticed this only happens when DMAs are initia...
We got the STM32MP157F-EV1 and struggle a bit with the understanding of OTPs. We cloned the STM32PRGFW-UTIL repository [1], put the dip switches into "forced USB boot for flashing" mode (all off) and uploaded the provided image: STM32PRGFW-UTIL\Proje...
