Hi ,NXP Engineers
At present, the data transmission channel of core A and core M through ipcf in our company is ok, but the current test finds that
Run the following command to ensure normal transmission
root@s32g399ardb3:/sys/kernel/ipc-shm-sample# echo 123 > ping
When we output more than 3 bytes, we will get an exception indicating that the access is illegal
root@s32g399ardb3:/sys/kernel/ipc-shm-sample# echo 1234 > ping
The function used to copy the data is memcpy，
The size of the pool we define is greater than 4 bytes
