Based on my experience with VF61 I would suggest an improvement to Rpmsg library.
I was thinking to a new configuration parameter to get the checksum of the firmware file.
Rpmsg_GetConfigInt (HANDLE hRpmsg, "FileChecksum", DWORD * pValue);
In this way the checksum (MD5, …) can be compared against the expected one and if they don’t match I can skip the call to
In this way it’s possible to show messages to the customer.
Otherwise, if the firmware is wrong and/or corrupted, most of the time after Rpmsg_Open() the A5 core crashes and the customer can’t understand what happened.
