/deploy/images folder missing after compiling distribution package for STM32MP
Hi, I used the below link for building OpenSTLinux Distribution.https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package As mentioned in the step 7 "Flashing the built image", there should be a /deploy/image folder for images. But i didn't fin...
Resolved! Debugging M4 with GDB from command line?
I would like to understand what the Eclipse IDE is doing to start the debugger, so that I can move away from using it. I much prefer CMake and other tools. I'd be grateful for any assistance. The wiki section for this is TBD.I'm not too familiar with...
Resolved! Maximum 4 virtual uarts can be created?
Hi,As i was testing the limit of how many virtual uarts i can create, i found that the limit is actually 4:Using debug tracing i can see that the channels get created inside the code (here i am creating 5 virtual uart) but only 4 ttyRPMSG are created...
Does a (embedded) flash page gets fully erased every write operation?
Good evening,since NAND flash can be addressed pagewise only (I guess STM32 flash is NAND) and I am able to write for e.g. a single byte to the page, will the whole page gets erased during every write operation? My presumption is that the page gets b...
Resolved! Inserting Breakpoint after Execution hangs when initializing Mutex or Semaphore in FreeRTOS
Hi,I am using the STM32MP157C-DK2 and so far i manged to make FREERTOS work flawlessly with OpenAMP and the tracing printf functions. I can insert breakpoint at any point without a problem. However, i start having issues when i declare a semaphore or...
Could not debug the OpenAMP_TTY_echo
Hi,I am following the tutorial of developing on M4 with the STM32MP1 but when I do the"debug as" to this project, it comes out an error.The STM32MP1 has connected to my PC through the STLINK usb; the boot0 and boot2 on the board have been set to "on"...
LPDDR2/3 support in STM32MP1 LFBGA448/LFBGA354
There's some inconsistency on the support of LPDDR2/3 on LFBGA448/LFBGA354 package. Page 16 of the datasheet lists that LPDDR is only supported on TFBGA257/361, which is consistent with the settings in CubeMX (LFBG* packages have on LPDDR option).How...
Bluetooth not working on STM32MP157C-DK2 board ("basic" image)
I'm trying to build an image for the STM32MP157C-DK2 board using the standard unmodified OpenSTLinux yocto build.The build is successful and the image boots fine, but Bluetooth does not work with the basic image (it works with the trusted image).Usin...
