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...
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...
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...
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"...
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...
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...
Hi, I trying to compile the OpenAMP_TTY_echo example, but I get these a lot of errors, attach a file.
Hi,We are currently using the STM32MP1 DK2 board for our project.We have to use FreeRTOS + UART7 and USART3 with DMA Our issue arise when FreeRTOS is used with an UART (USART3 or UART7 in our case) which use the DMA.We have reduced the project to the...
I am programming a STM32MP157C-DK2 board using System Workbench. I have been able to run the OpenAMP_TTY_echo example project without trouble. Then I created a new project and generated OpenAMP middleware from CubeMX. No trouble while compiling and u...
Hi,I would like to compile with the GNU toolchain directly on the device, without the use of cross-compilation. it's possible?In which way can i do that?
