Hi,

Im trying some bare metal development on the BPI-F3 (Spacemit K1). But I cant get JTAG to work without running linux (when booted linux the config works). Booting using uboot (BOOTELF) command

Does anybody know which register set to enable JTAG on the pins?

errors:

Found the reason myself it was because the cores weren’t started yet
