we are developing the application by using STM32MP1 processor in bare metal.we are able to wake up Cortex A7-1 from Cortex A7-0 both are working fine. Now we tried to wake up Cortex M4 from Cortex A7-0,But we are unable to wakeup Cortex M4 from Corte...
I have custom board based on STM32MP153C.This board has 7 serial ports. I configuring these ports with STM32MP1Cube.After linux boot 4 of these serial ports become disabled Driver doesn't probe them and they are in "disabled" state in /sys/firmware/d...
we are working on STM32MP1 in UBOOT 2018 version .we are trying to access the EMMC from UBOOT by using following commands in the below linkhttps://develop.phytec.com/phycore-imx7/linux/pd18.1.0/how-to-guides/flashing-and-booting-from-emmcEMMC is de...
Hi,For SD, we just take the card to PC, write image directly, take about few minutes for 4GBFor EMMC, we have to use STM32CubeProgram and this take so long, up to an hourI am using USB, not serial. For Serial, it could be a day for 115200bps.We are n...
We have a custom board developed on stm32mp157 with openstlinux-5.10.10 (dunfell). I want to monitor the GPU consumption, and as per this link, I enabled the debugfs flag from menuconfig. However, upon deploying the image to target, no /gc folder was...
I built u-boot for stm32mp157a-dk1 board with basic boot mode:Defconfig: stm32mp15_basic_defconfigDevice Tree: stm32mp157a-dk1I got this error at starting u-boot and if I try to read/write from/to OTP register:stm32mp1_clk_get_id: clk id 69 not found...
.. previously I had STM32MP157D-DK1 on work, there DFU works Ok,but now bought STM32MP157F-DK2 for home, there's no any sign of connection,reset button do not affect on STlink led, meanwhile stlink/2 itself - works and other USBs - is Ok.Maybe it's a...
Hi!I am using a STM32MP157C-DK2 board to communicate via CAN. To do this, I have created a program in STM32CubeIDE and set the FDCAN parameters:Classic mode.150KB/s nominal baud rate.HSE clock source (24MH) I have been testing in engineering mode and...
