> @michallenc - Please check the order of of operation in the `imxrt_caninitialize` path. `imxrt_ifdown` is called on the interface with out an initialize. The SOFT RESET will fail as the clock is not running and return here, https://github.com/michallenc/incubator-nuttx/blob/4b65e3647124e935264725d014310a3e9ae4a7cf/arch/arm/src/imxrt/imxrt_flexcan.c#L1746 > > Adding imxrt_initialize(priv) here https://github.com/michallenc/incubator-nuttx/blob/4b65e3647124e935264725d014310a3e9ae4a7cf/arch/arm/src/imxrt/imxrt_flexcan.c#L1941 > > will fix it That´s weird. What configuration are you running? I don´t seem to be getting the same problem: ``` nsh> imxrt_caninitialize: callbacks done imxrt_reset: MB 0 0x401d0080 imxrt_reset: MB 0 0x401d0084 imxrt_reset: MB 1 0x401d0090 imxrt_reset: MB 1 0x401d0094 imxrt_reset: MB 2 0x401d00a0 imxrt_reset: MB 2 0x401d00a4 imxrt_reset: MB 3 0x401d00b0 imxrt_reset: MB 3 0x401d00b4 imxrt_reset: MB 4 0x401d00c0 imxrt_reset: MB 4 0x401d00c4 imxrt_reset: MB 5 0x401d00d0 imxrt_reset: MB 5 0x401d00d4 imxrt_reset: MB 6 0x401d00e0 imxrt_reset: MB 6 0x401d00e4 imxrt_reset: MB 7 0x401d00f0 imxrt_reset: MB 7 0x401d00f4 imxrt_reset: MB 8 0x401d0100 imxrt_reset: MB 8 0x401d0104 imxrt_reset: MB 9 0x401d0110 imxrt_reset: MB 9 0x401d0114 imxrt_reset: MB 10 0x401d0120 imxrt_reset: MB 10 0x401d0124 imxrt_reset: MB 11 0x401d0130 imxrt_reset: MB 11 0x401d0134 imxrt_reset: MB 12 0x401d0140 imxrt_reset: MB 12 0x401d0144 imxrt_reset: MB 13 0x401d0150 imxrt_reset: MB 13 0x401d0154 netdev_register: Registered dev: can0 ``` I can´t test the fix as the problem for some reason doesn´t occur in my board, but if you can fix it and test it then please make the PR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
