Hi,
1. trying to enable Wilink8 on am335x custom board with 5.10.153 linux kernel;
git://git.ti.com/git/ti-linux-kernel/ti-linux-kernel.git with 5.10.153
2. as per this link https://www.ti.com/lit/ug/swru561a/swru561a.pdf?ts=1688530813079&ref_url=https%253A%252F%252Fwww.google.com%252F
added all the flags into kernel config.
3. but after below line, board is paused and rebooting.
[ 0.155901] thermal_sys: Registered thermal governor 'step_wise'
[ 0.156116] cpuidle: using governor ladder
[ 0.156296] cpuidle: using governor menu
[ 2.297461] hw-breakpoint: debug architecture 0x4 unsupported.
please refer attached log,kernel config and dts for same.
please suggest or any direction for same that would helpfull.
Thanks in advanced.
