Is it possible to apply ULINK2+KEIL IDE to debug nRF24LU1+?

[Pica]

Dear Sir: I have designed my board with nRF24LU1+, and I want to debug it through ULINK2 JTAG. However, it seems not working.

Would you please share me with some ideas?

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")

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. ~@@~

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

Have you asked Keil ?

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?
