PEAK CAN to USB use in STM32 bootloader
Dear All,
I had some items with the CAN bootloader in the STM32 (F446, in particular). Basically, the communication was not stable with a lot of BUSHEAVY, BUSLIGHT, OVERRUN and BUS-OFF issues, while using a PEAK CAN to USB converter with the drivers and library from PEAK Systems for C-Builder.
In another thread, Jeroen3 suggested to use a Kvaser due to USB issues, which triggered me to play with the bittiming. With the available BitRateTool from PEAK, I have chosen a Btr0Btr1 value with a higher Synch. Jump Width (SJW) of 0xC33A instead of the standard 0x031C, which made my issues go away. I only tryed this other value, maybe others may work for you too.
Since I got the trigger from this community, I thought: Let's post my solution.
Regards, Folkert
