hi all When testing SPI2 in jekpack 6.0, some issues occurred. Currently, I am using SPI2 to connect to MCP2518FD, but the following error is reported. i use the customboard [ 49.127133] ------------[ cut here ]------------ [ 49.127169] WARNING: CPU: 7 PID: 818 at drivers/spi/spi-tegra114.c:1…

ok is my dts file example.dts.txt (363.0 KB)

this issue is same as AGX Orin spi-tegra114 c260000.spi crashed when sending large amounts of data in JetPack 6.0 - #13 by bbear953308023 and i set the max dma buffer to 256 , the spi can up well but . the mcp2518fd in this spi , cannot recv any message and just can only send 1 can package.

hello @KevinFFF this issue has been block our project , did you have any suggestions?

this change seems work but, mcp2518fd still cannot send/receive CAN data packets

[image] duztfeng: mcp2518fd still cannot send/receive CAN data packets Is there the data on SPI bus? Could you also verify using MCP2518FD on SPI1? We’ve verified it working on the devkit with JP6.2.

hi @KevinFFF i update my jetpack to 36.4， this issue still persists. this bus has spi data , because the mcp2518fd can be set up, and set params but can not send or recv can message. our board has 3 mcp2518fd , there connected to spi1: spi@3210000 、 spi2 spi@c260000 、spi@3230000 only the …

[image] duztfeng: our board has 3 mcp2518fd , there connected to spi1: spi@3210000 、 spi2 spi@c260000 、spi@3230000 only the spi2 spi@c260000 has this issue. Do you mean that spi1 and spi3 work as expected for MCP251FD but you still hit the issue for spi@c260000? If so, please run the follow…

MCP2518FD is connected on SPI interface.
Please apply the patch from Jetson orin nano SPI Speed not changing - #9 by KevinFFF to check if it could help.
