This config covers the 4x Cortex A53 CPUs. A custom connector is required from J14 to standard ARM JTAG on v1 boards. However v2 hardware should have a standard FTSH-105-01-L-DV connector. Pinmuxing code to enable JTAG pins is included in l-loader-poplar repository, so board is flashed with open source code, JTAG is available at very early boot. Alternatively the following pokes can be issued from U-Boot to enable JTAG (e.g. to debug hisilicon SDK). mw 0xf8a210ec 0x130; mw 0xf8a210f0 0x130; mw 0xf8a210f4 0x130; mw 0xf8a210f8 0x130; mw 0xf8a210fc 0x130; mw 0xf8a21100 0x130; Change-Id: I2b83dfcb3dc5461c1620f94dd99aa7b31fdda59b Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Reviewed-on: http://openocd.zylin.com/4161 Tested-by: jenkins Reviewed-by: Jiri Kastner <cz172638@gmail.com> Reviewed-by: Paul Fertser <fercerpav@gmail.com>
