USB port 2 cannot be recognized!
We built a customised board based on the stm32mp175c-dk2, with some changes, one of which was the addition of two USB type-c connectors.When I try to use the USB in DFU mode, everything works fine, as long as the boot switch is turned off. When I tur...
Resolved! Unable get interrupts to Cortex A7_1 in STM32MP157
helloWe are using STM32MP157A-dk1 evaluation board. To this we are writing bare metal code in SEGGER Embedded Studio.Actually, We have enabled group and set enable registers for respected SGI and PPI interrupts in GICC and GICD registers. By this we ...
A callback() for GPIO in the A7-core on the Linux side of the STM32MP157F
Hello,I'm working with STM32MP1-DK2. I want to run a project on it.I need to implement a callback function in the A7-core (Linux side) to read a pin whenever a signal comes in (on the rising or falling edges).Actually, I need to have a callback() fun...
OPENAMP send data from M4 to A7 and wait until RX buffer is free
Hello,I need to send several kilobytes of data from the M4 to the A7. However, I am experiencing data loss during this transfer. Is there a function that waits on the M4 side, until the A7 has collected all data from the tty./* * Channel direction a...
Resolved! Using STLink with STM32MP151 - illegal access error
We have a custom PCB application that uses the STM32MP151CAC1 as the main CPU. We have tried to use an STLink v3 to connect to the chip over SWD, but have been unable to do so. The chip (through UART4) throws the following error when I try to connect...
Resolved! STM32157f-dk2 getting started not working for compile and flashing kernel
Hi there, I just received the STM32157f-dk2 discovery board, and I just started to dive into the tutorials. I am trying to simply follow the step to just cross-compile and flash the kernel image. When I complete all the steps and reboot the board, th...
STM32MP157D using otg as a device with micro-b connector ,and computer cannot find it.
I'm trying to set otg on stm32mp157d in device only mode, according to the guidance on OTG device tree configuration - stm32mpu (stmicroelectronics.cn), &usbotg_hs { compatible = "st,stm32mp15-hsotg", "snps,dwc2"; phys = <&usbphyc_port1 0>; ...
Using STM32MP157 with OpenAmp echo example ttyRPMSG0 is missing - sometimes - why ?
I am new to STM32 boards and IDE but have an STM32MP157A-DK1 board which came with an SD Card / OS on it. We want to make our own OS image using the ST linux.In the downloads accompanying the workshop videos we have the DK2_TIMER1_OpenAmp_Solution to...
