DAP firmware not working

Hi,
I ordered four HAT units from local Fab, i have carefully checked soldering then plugged it into USB, CRP DISABLD volume could enumerate after the first power up. Then i follow instructions to flash the DAP by using lpc11u35_6lowpan_borderrouterhat_if_crc.bin.

However after flash, (both windows, Linux and mac dd, 2.xx sec write time), DAP power LED not light up, and USB device could not be detected by using lsusb nor dmesg.

I am still checking my board against design files in the repo. Could you provide me some hardware debugging hint?

P.S. T2 (usb mos gate pin become 0v after flash, but LED power pin is high) have been double checked, firmware could be working, but the USB port is NOT.

Hi,

Could you let me know the exact schematics you are using? And also Bill of materials would help greatly.

Are you seeing the device always showing as CRP DISABLD, all the time?

I cloned this repo:link. I think it's version V1.1.0

I have CRP DISABLD when first boot, but after flashing it, the USB doesn't enumerate anymore.

Thanks for your reply.
