hi, we are using stm32MP157A ,in this we enabled timer2 APB1 and APB2 clock for timers . When we trying to write timer 2 the processor gets hanged . For this what may be the issue. In the similar way i did it for the UART4 its working fine . Where ...
I want to use open source utilities to load U-boot into SRAM in "Serial mode". Is it possible?P.S. As I can see, there is an article about it on ST Wiki, but an access to it is restricted for regular users: https://wiki.st.com/stm32mpu/wiki/How_to_lo...
Is there also an ARM version of the SDK to develop the Modules.because here I only found a X86 versionhttps://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Installing_the_SDK
We are using a STM32MP157 chip on a custom low-power design and don't need the Cortex M4 core. We would like to disable it properly to reduce power consumption and also remove dedicated support in linux kernel.Is there any recommended way to do this ...
After DDR3 (16 bit) training complete, registers are:DX0DQSTR=0x3DB03001, DX1DQSTR=0x3DB03001Should I redesign CPU board or these values are suitable?
HI ,How can i install mongodb , mariadb and postgresql on stm32mp1?Is there support for databases provided for stm32mp1?
We are seeing some strange behavior on our stm32mp157 system exiting suspend mode.This is not a 'weston' build, so we enter (deep) suspend mode by executing "echo mem > /sys/power/state" and the system powers down and enters low power.root@stm32mp157...
