Hi all,I have a MPC5200B based system with a 16-bit peripheral attached to the Local Bus, and I am looking into possibilities to use BestComm for the data transfer.
I found Grant Likely's cool 'mpc5200-localplus-test.c' driver which demonstrates this using the 'gen_bd' driver, and which is apparently a great starting point.
However, I also have to (a) 32-bit endianess-swap the data and (b) calculate a 32-bit crc on it. Of course, this is possible with the buffers using the cpu, but I saw some remarks that the Bestcomm engine also includes functions which can perform swapping and crc calculation. I believe it would unload the cpu if the BestComm engine could perform these tasks, but I cannot find a good documentation/example for that. Does anyone know any pointers for that? Or maybe even a tool to create the bestcomm tasks from a 'readable' source?
Thanks in advance, Albrecht.
