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...

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>; ...

what can be the maximum packet size to be sent over OpenAmp from the M4 to the A7. ,is there any limitation.?? How we can maximize the data throughput over OpenAMP.

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...

We are building a board based on ST32mp157c and have problems enabling USB port 1. We did not include the ECMF02-2AMX6 choke. Could this be the problem?

We have also deleted the OTG (USBC) hardware and have commented out the code to check for the OTG power., Otherwise we are using the basic defconfig and the DK2 devtree.
