A20-OLinuXino-MICRO user's manual
on the debugger you have and the type of its connector (20-pin JTAG, 10-pin JTAG, etc).
Software-wise – the JTAG should be enabled by default but you might also edit the script.bin/fex
file that contains special JTAG part. Please check here:
sunxi.org/Fex_Guide#.5Bjtag_para.5D
; the [jtag_para] part.
The real issue would be finding piece of software that has Allwinner A20 support. The sunxi
community has some experimental configuration files for A10 and A13 boards I believe, but they
were never tested by an Olimex employee.
Furthermore, we have no experience with the JTAG debug, we have not performed any JTAG
debug sessions ourselves.
