On ecosystem 4.1 and git version 2.39.1 there is an error when you do devtool modify tf-a-stm32mp and bitbake tf-a-stm32mp. The error is Command '['git', 'submodule--helper', 'list']' returned non-zero exit status 128. After a bit of searching there ...
I would like to set the low-power timer as wake up source to wake up the Linux from sleep mode with some periodic time, let's see every 5 minutes. All I have found is pwm and counter examples here: https://wiki.st.com/stm32mpu/wiki/LPTIM_device_tree_...
I've tried following the examples given here and here, but it will not work. I just want to enable a pull up resistor in the DTS file. Here is my DTS file. If anyone can please tell me why it's not working I would appreciate it. /dts-v1/; #include ...
I want to generete interrupt for specific value of TIM->CNT TIM1->DIER |= TIM_IT_CC1; TIM1->CCR1 = myVal;I use only above. if(TIM_GetITStatus(TIM1,TIM_IT_CC1) != RESET){ //when interrupt generete here ,CCR1 is not equal my value } I'm so confused w...
Can some one help me to know what would be the default factory OTP settings on the processor - STM32MP157FAA1 - or should it be set by the User? Does the Default Comes with SDMMC1 set for the Boot?If I need to change from SDMMC1 to SDMMC2 as the Pri...
Hi,We want to boot cortex M4 from cortex A7 in baremetal in RETRAM. We have followed below steps 1.we are setting BOOT MCU bit in RCC global control register(Offset :0x10C). 2.I am restting MCURST bit in RCC global reset control set register(offset:...
Hi,I encounter an extraordinary problem with STPMIC1APQR. When powering on the board without loading any images voltages on each section are as described in the PMIC documentation. When I start fsbl the voltages change, and increase not as described ...
I have a custom board with a STM32MP157AAB3 and I am trying to boot it with the SD card. I have tested the SD card on a STM32MP157C-DK2 and it boots to Linux fine. When I probe the SD card lines, I can see the clock is toggling for a long time and ...
I try to spi communication between my board with STM32MP157AACx microprocessor and STM32F429 disco board. I write code using bare metal for master side(my board), using HAL library for slave board(STM32F429). My problem is that I can't receive data f...
Hi,I am doing "4.Adding an external out-of-tree Linux kernel module" at the below link.https://wiki.st.com/stm32mpu/wiki/How_to_cross-compile_with_the_Distribution_PackageI am suffering from a module building problem and got the message below. I don'...
