The nRFgo motherboard has headers for external flashing and external debugging. As long as your external board has both JTAG and FLASH SPI routed out, it shall be possible to flash and perform jtag debugging. Check out the user guide for the pin-outs: www.nordicsemi.com/.../12867035

Dear Hakon: So, there is no way to do on-chip debug on my own design board, right? The only way is to debug on nRFgo Kit and install the built image to my board?

Have you asked Keil ?

Hi,

The Ulink2 is aimed for ARM based CPU cores: www.keil.com/.../

The Ulink1 devices are 8051-compatible, but unfortunately, they are mostly vendor specific due to 8051 not having a dedicated debugger circuit (remember: the original 8051 core is ~13 years older than JTAG).

If you want to use the debugger interface on the nRF24LU1+/nRF24LE1, the cheapest option today is to use the nRFgo StarterKit: www.nordicsemi.com/.../nRFgo-Starter-Kit

Cheers, Håkon

Dear Awneil: Yes, I indeed read the document and there is one page (p.175) says I can do on-chip debugging through JTAG.

But, I can't get it working. ~@@~

There is no mention of any on-chip debug interface on the Product Page:

www.nordicsemi.com/.../nRF24LU1P

Have you looked at the Datasheet ("Product Specification")
