Hello guys,
I thought LPC1226 was supported, but when I try debugging the target
with GDB or use 'program' command it crashes with saying:
Error: BUG: unknown Part ID encountered: 0x3660002b
However it does work with basic functionality: I can halt, access
memory, write to RAM and peripheral registers.
The board is custom-made, but at this point I don't think this is
anything board-specific. Now, the details from my last attempt: I'm
running the OpenOCD on Debian 9 (x86_64) with:
/usr/bin/openocd -f jlink.tcl
where contents of 'jlink.tcl' are:
# Use J-Link over SWD transport
source [find interface/jlink.cfg]
transport select swd
# Load LPC12xx configuration
source [find target/lpc12xx.cfg]
# Configure to drive nRESET/SRST (not default)
reset_config srst_only
# Select 10MHz debug clock in accordance to
# Keil default configuration
adapter_khz 10000
then, issuing commands over telnet interface I get such output (telnet
interactive input intermixed):

So, uhmm, it's a bug, isn't it?
