I need to store a password for encryption in otp registers. I configured device tree in tfa:&bsec{ status = "okay"; secure-status = "okay"; enc_pass: enc_pass@0x170 { reg = <0x170 0x10>; st,non-secure-otp; };};&nvmem_layout { nvmem-cells = <&enc_p...
Hi,I created a project in Cube-IDE . It is a simple PWM timer Project which planned to be run on A7 processor of the STM32MP1 . I established configurations in Cube-MX and generated the code into the Cube IDE. After that, I moved the .dts file which...
Hello,Is there a way to access the Tamper or backup registers or the backup sram from the MCU? Or is it physically imposible to do so?Edit:I am still looking for an answer, I just saw in the RCC registers that I can enable BKPSRAM bits to:enable the ...
I followed the steps on the below webpage to enable Wireless on my STM32MP1. It would be great to see these instructions added to the wiki.st.com http://trac.gateworks.com/wiki/Yocto/Wireless
As we tested, from word 24 to 32, once write 0xFFFFFFFF ( all 32 bit turn to 1), is there any way to set back to 0x00000000?And same for bit 59 to 95 (free for user)?

We designed original board using STM32MP153D.We cannot boot by U-boot.When booting via USB, the Hash check (hash_sha256_check) of the page in the init_runtime of opte_os fails when booting U-Boot (see console log below).The page that fails is differe...
Hello， I use the STM32CubeProgrammer to write Stm32mp157c board boot TF card. But it fail. How can I fix this problem?
Hi,We want to develop bare metal application for Stm32mp157A processor. So we need the DDR initialization Source code in bare metal for Stm32mp157A processor. Can you help us in this.
