@xiaoxiang781216 please take a look at error #14: https://acassis.wordpress.com/2023/06/20/nuttx-ci-github-failures-list/ CI failed to downloaded littlefs for sim test. Is that possible to detect the download fail and retry more 2 times before assuming it is an error? |

Summary
The timing mask for the can's ctrl1 register excludes the propagation segment bits. This results in incorrect timing when configuring bitrate at runtime with SIOCSCANBITRATE when the bitrate to timeseg algorithm selects a different propseg value.
Impact
Incorrect can timing configuration when moving between rates at runtime.
Testing
s32k1xx HW testing: moving between several speeds both in listen only and while actively participating on the network.
