Anyone have a clue what might be wrong with attempting to connect to a QCA4020 using the J-Link mini programmer.

Connecting ...
 - Connecting via USB to probe/ programmer device 0
 - Probe/ Programmer firmware: J-Link EDU Mini V1 compiled May 18 2022 17:09:10
 - Device "CORTEX-M4" selected.
 - Target interface speed: 1000 kHz (Fixed)
 - VTarget = 3.172V
 - TotalIRLen = ?, IRPrint = 0x..000000000000000000000000
 - Failed to identify target. Resetting via Reset pin and trying again.
 - TotalIRLen = ?, IRPrint = 0x..000000000000000000000000
 - Executing init sequence ...
  - ERROR: Could not perform target reset
 - ERROR: Failed to connect.
Could not perform custom init sequence.

Are the JTAG connections listed

I have corrected the missing 120K pullup resistor on reset

Thank you in advance
Dante

Crud,

Looks like you cannot put images in the posts

How does one put in figures - like schematics snippets for reference

I have a J-Link mini working for a long time know. If you could list how you did connect it I can compare it with my setup
