I can't seem to make a connection between my segger jlink to ProxMark3 easy 512.
In JLinkExe, after running "h", jlink is complaining:
**************************
WARNING: RESET (pin 15) high, but should be low. Please check target hardware.
**************************I've tried resetting the protection bits on the atmel (following: http://www.proxmark.org/forum/viewtopic.php?pid=34445#p34445):
* While the PM3E was powered up:
* connecting/shorting Pin 55 to v3.3, for 1 second.
* power cycled the board.
Hardware:
* Segger J Link (clone, latest firmware)
* Proxmark3 Easy 512 (AT91SAM7S512)
OS: Mac OSX 10.15.4 Catalina
Brew has Proxmark installed.
This is what I've tried, in as much relevant details as possible:
Connected the
(Proxmark 3 Easy <=> Segger JLink)
TMS <=> TMS
TDI <=> TDI
TDO <=> TDO
TCK <=> TCK
GND <=> GND
3.3V <=> VTref (pin1), I've tried pin 2 as well.using a continuity tester, at start of one header to another. All good connections.
Both the JTAG and Proxmark are plugged into the computer via USB. the headers are connected together.
