Hi Garrett,
Would you like to apply this patch?
The priority of TB1 is lower than TFs, if TB1 was assigned to the CPU
which scheduling TF, TB1 will not have chance to run.
I raise the priority of TB1, the new priority of TB1 is higher than TF
and TL, and still lower than TP.
After applying the following patch, test will work correctly.
Regards
Bian
