[SOLVED] Error: AP[0] selected for communication is not an AHB-AP.

Hello,

I am trying to connect J-Link Ultra+ to Vorago VA10820 MCU on a custom board with J-Flash. But when I try to detect devices in JTAG chain, I get error: AP[0] selected for communication is not an AHB-AP. Please see attached picture of my configured J-Flash project. Could you please help me with this issue?

Best regards

Hello,

Thank you for your inquiry.
Such an issue is not known to us.
It seems that you are using a relatively old J-Link software version.
To make sure this is not an effect that has already been fixed could you download the latest J-Link software version and try it out?

Hello Nino,

Thank you for your reply. I will update my J-Link software to the newest version. Also I have managed to find the cause of the problem today. There was an error in the pcb layout, so the MCU clock was not working. Now it works fine.

Best regards
