Hi,
SAMA5D27 (custom board) - trying to complete the port and also check that the CAN interface works on the board, so I'm trying to use the CAN example app. The drivers appear to be registered (I see /dev/can0 and /dev/can1) but the CAN example app crashes when trying to open /dev/can0 and I can't see why. I am hindered in debugging this fully as yet since: a. I am new to Nuttx and haven't yet sussed how to enable any low level debug-type stuff (I have used menuconfig to enable anything that seems to be related but I'm sure I missed stuff) b. I haven't yet coerced my Eclipse IDE (under Windows 10, but code configured and compiled using Windows WSL) to "see" the source code properly to enable me to insert breakpoints (Segger J-link). Not wedded to Eclipse, but it is a known entity for me and at least downloads/runs/debugs the board!) Can anyone point me in the direction of why, or a way to find out why, the call to open the device would crash the board rather than return an error? Other devices (such as Flexcom USARTs open OK and work - well, after I fixed some arch issues for Flexcoms on the SAMA5 anyway!!). The board-specific code (sam_can.c) I am using is based on the code for the sama5d2-xult board and seems pretty trivial, and largely similar to many other architectures and boards. Many thanks, Tim.
