Im using the 112 pins 52235 on custom board, and im trying to run the Coldfire_Lite_FTP_server on it, but in mcf5223_ePHY_init()  the FEC an EPHY registers are different compared to M52233DEMO board.
 
The program hangs at (void)fec_mii_read(0, 0, &reg0); in mcf5223_ePHY_init() cause it gets a timeout for MII interrupt.
 
Could someone please tell me if theres a difference between the 80 and 112 pins cpus? Why the software does not work if they are supposed to be the same cpus?
 
Thank you.
