- I corrected the last post. TDO is not pulled up or down on the SOM.
- 12:55 PM PCB Development: RE: JTAG TRSTn pulldown and other JTAG pullups
- Hello,
The SOM includes the following on the JTAG related lines:
* 4.7K Pulldown on TRSTn
* 4.7k Pullup to VDD... - The AM62x datasheet states (in section 6.4) that an external pulldown is required on the TRSTn line. Is this implemen...
