I am currently running in Engineering mode. In this application I am not using Linux on the A7, so I want to enable the trace SWO output from the M4 processor.
Hi everyone!I see unexpected values when measuring VREFINT. The ADC measures around 1.18V, on some boards even 1.16V, which is outside the tolerance according to the datasheet: Reading the calibration value VREFIN_CAL from OTP memory returns a value ...
Hello,I'm trying to trigger a conversion in a frequency of 4700 HZ. To do so I used cubeMX to configure the ADC to work at DMA circular mode and to be triggered by TIM4 trigger out event on the rising edge. I made sure to activate DMA in high priorit...
Hi,We see signing + encryption bootloader on STM32MP13xx,But on STM32MP15xx, there is only signing. The raw binary still start from offset 256 of the signed file. This only make sure the board doesn't run a strange bootloader, but doesn't prevent som...
I need giga ethernet working on linux.Is it possible with the STM32MP?Please let me know if you have any test results with iperf.Thank you for answers.
From instructions, I opened two console: Console 1: openocd -f board/stm32mp15x_dk2.cfg This looks good as output: ``` ... Info : stm32mp15x.cm4: Cortex-M4 r0p1 processor detected Info : stm32mp15x.cm4: target has 6 breakpoints, 4 watchpoints Info ...
When i tried the commend below (<Your_full_path_to> was already corrected to the path that content Setup.gdb), ```gdbgui -g "arm-ostl-linux-gnueabi-gdb -x <Your_full_path_to>/Setup.gdb"```I would like to use ST-Link for debug uboot, but the web brows...
There is a'ifdef CONFIG_SPL_BUILD' in stm32mp1.h, Makefile or many files, but there is no setting in the Kconfig file.
From user manual, from OTP word 59th for user to store sensitive information, meaning there is a way to prevent read them by STM32cube tool for non-secure application.We see the way to lock them which mean can't not change values, any document that t...
Hi,I usestm32mp157c and the filesystem runs emmc default. But I want it to change it and run at ramfs. I addedCONFIG_BLK_DEV_INITRD=yCONFIG_RD_GZIP=yCONFIG_RD_BZIP2=yCONFIG_RD_LZMA=yCONFIG_RD_XZ=yCONFIG_RD_LZO=yCONFIG_RD_LZ4=yin kernel config file. A...
