2 CANFD on PIC32MK1024MCM100

[jigneshmoradiya1]

Hi,

Data Bit Timing is not correctly configured for 4000 Kbps Bit Rate because Calculated Bit Rate is 0 and Error % is 100%. CAN-FD Clock Frequency should be configured 20MHz/40MHz/80MHz as per datasheet (https://ww1.microchip.com/downloads/en/DeviceDoc/PIC32MK-GPK-MCM-with-CAN-FD-Family-DataSheet-DS60001519E.pdf, Page#463).
For example, Please find the MHC configuration for CAN-FD clock frequency 20MHz, Nominal Bit Rate 500 Kbps and Data Bit Rate 4000 Kbps as below.

Thank you.

hi,

Thanks for your comment.
I tried to config 2 CAN channel with your proposal => same probleme, PIC don't start.
I use REFCLK4 to 20Mhz but nothing

After many tried, the problem appear only when i add CAN2.
Actually my PIC works with CAN1, CAN3, CAN4 and UART2 ON.

@raf6410 , CAN Bit Timing should be configured in MHC configuration as mentioned in above screenshot. Closing the ticket now. In case of any issue please feel free to reopen ticket.
