HI,I am working on a custom STM32MP151AAC3 board, and working on OpenSTLinux 4.10 distribution package.Now I can connect to the board through UART4(PB2 and PG11) by STM32CubeProgrammer, and I want to tune the DDR3 to verify the design. I need the u-b...
when we run the minicom -D /dev/ttyACM0then it show below errorminicom: cannot open /dev/ttyACM0: Permission deniedhow i can solve this problem ?
Hello everyone,I have the stm32mp157c-dk2 for performance evaluations. Our goal is to check if the CPU/GPU performance is good enough for our next productm which will be used as a GUI frontend.I built the openstlinux (mickledore) as-is from github su...
On a proprietary board based on STM32MP157AAA, code was created on the M4 core for reading 11 analog gates managed in DMA (end of sequence interrupt) of ADC1 and ADC2 in independent mode with conversion start via software executed cyclically. The adc...
hi, i am doing a project related to fdcan on m4 kernel of stm32mp157d-dk1, i have configured it like the tutorial video on youtube of stm32 https://www.youtube.com/watch?v=xGRvVKfs2-0&ab_channel= STMicroelectronics, but they don't work, please help m...
Hello,currently, I'm in the production phase of my product which is based on stm32mp153. Unfortunately, I have a huge problem with setting the password for root.First I commented debug-tweks in local.conf.I added INHERIT += "extrausers" EXTRA_USERS_...
Hi, I have a custom board with a stm32mp153. I was able to get past the trusted bootloader and into optee. It builds the mmu map and then panics when checking it. I am able to partially step through building the table and the memory starts to get ...
I am testing our custom board with stm32mp153a and I have customized the DDR utility so that the uart and pmic work. I have used the RAM timings from cubemx that kind of work with TF-a. I have the PLL2 values that also work with TF-a. I get a DDR ...
I have update uImage and dtb but I get this error during boot Starting kernel ... E/TC:0 Panic 'Watchdog' at /usr/src/debug/optee-os-stm32mp/3.19.0-stm32mp-r1-r0/core/drivers/stm32_iwdg.c:198 <stm32_iwdg_it_handler>E/TC:0 TEE load address @ 0xde0000...
Hello everyone, we have designed a custom stm32mp157f based board, trying to bring it up. I can get past the first stage boot loader and quite deep into OPTEE boot. The boot stops when OPTEE panics at ETZPC Probe (see below). If I disable the ETZPC i...
