In my custom FSBL on an STM32MP135AAE3, everything runs great except anytime I try to modify one of the GIC flags it pretty much ignores me completely (when I read it back, my changed bits aren't changed). I'm guessing this is some kind of trust zon...
Does the stm32mp157 have an ESV or is there one in progress?
Hello everybody.On STM32MP2, is it possible to operate only the M33 like a microcontroller, without booting the A35? Also, if only the M33 is operated, can major peripherals such as I2C and Ethernet be controlled from the M33? (I assume that PCIe wou...
I am building a custom Yocto image for STM32MP1 (STM32MP157) using ST OpenSTLinux (dunfell-based) and I am facing a persistent U-Boot build failure.Environment:SoC: STM32MP157 (custom board)Yocto: ST OpenSTLinux (dunfell)U-Boot: v2020.10-stm32mp-r2.2...
I've got an STM32MP135AAE3 for which I'm writing my own FSBL. It's basically working!There are two scenarios:1) Chip set to serial boot; the BootROM wakes up and I use STM32_Programmer_CLI.exe to send it my FSBL which it stores in SYSRAM, BootROM th...
Hello,unlike the STM32MP157F-DK2 the STM32MP257F-DK is not equipped with an Touch/LCD.Is it possible to use an identical/similar LCD with the STM32MP257F-DK (that means: are the appropriate connections on the board)?Marc
Linux kernel, Yocto project, etc. each has their LTS strategy, does ST has similar plan for its OpenSTLinux?
Hi,I am trying to understand and test secure boot on STM32MP1. I was able to compile and boot unsigned tf-a. boot failed as expected as it is not verified.generated keys.Now how to burn these below hash file? can we burn into flash and test without u...
Hello Team,I am currently working on QuadSPI with MDMA, but I am unable to locate the driver code for this functionality.Could you please provide the required driver code?For reference, I am working on the STM32MP133F series.Regards,Sreedhar Kaduru...
