Hi ti,
I was attempting to test the MCAN interface on the AM62x-SK board by connecting an external transceiver (TCAN1051HGVDR) to a 40-pin expansion connector (pins 8 and 10), as described in the link below.
software-dl.ti.com/.../MCAN.html .
I gave commands up to candump can0 on the RX as well as on the TX (cansend can0 123#DEADBEEF). But here I am facing an issue while trying to send data from TX (cansend can0 123#DEADBEEF), and I am getting (m_can_platform 20701000.can can0: bus-off).
I don't know how to fix this issue; please help me on this issue.I have attached the log of the TX window, which follows below.
