I have 2 Olimex CAN-EVB boxes; 1 of 2017 and 1 of last year. I made a CAN application with the first one and it is working for most standard bitrates, however not lower than 25 MB/sec. This was a known problem and is related to the 80 MHz APB clock. ...
understanding. Now the reference manual states that the APB clock is derived from the CPU input clock. So for a PLL of 480 MHz according to the manual that would mean 480/4 = 120 MHz. Yet everything states that the APB clock is 80 MHz. Can anybody help me out what I did get ...
