JTAG Debug Specification for nRF24LE

[kaosad]

Hi Nordic team,

Do you publish the JTAG Debug specification for nRF24LE? I am interested in developing a low-cost debug probe for nRF24LE for SDCDB.

The nRF24LE1 only support programming via SPI not JTAG. You can find the instruction on how to do flash programming via SPI at section 6.3.5 in the nRF24LE1 spec.

I am interested in debugging and not programming. The nRF24L _Product_Specification_rev1_6 document mentioned that HW debugger support (section 27) is available. And the JTAG pins are (on 32-pin chip):

P1.3 => OCITO (out)

P1.2 => OCITDO (out)

P1.1 => OCITDI (in)

P1.0 => OCITMS (in)

P0.7 => OCITCK (in)

The document however lacks information on JTAG debugging. It would be useful if such information is available. I am sure many out there who want to be able to do hardware debugging.
