Hello,
I having problems to debug M4 software on IMX8M, I follow the guide on Using JLink Debugger for M4 software on IMX8M but J-LINK Server Can't find any processor on JTAG.
I think witch the problem may be in my JTAG circuit, mainly the o use of a pull-down on JTAG_TCK.
Can you help me reviewing my JTAG circuit.
Thanks
Regards
JTAG_TCK has internal 27K Pull up, why is a10K pull down required?
Hi Leandro
i.MX8M EVK uses the same connection so seems there is no problem using it.

Hi Leandro
How is you JTAG_MOD connected ? Is it properly pulled down ?
