Info : Listening on port 3333 for gdb connections Info : starting gdb server for lpc2378.cpu on 3333 Info : lpc2378.cpu: hardware has 2 breakpoint/watchpoint units Info : JTAG tap: lpc2378.cpu tap/device found: 0x4f1f0f0f (mfg: 0x787 (), part: 0xf1f0, ver: 0x4)Įrror: EmbeddedICE v7 handling might be broken ![]() Info : Versaloon(0x15)by Simon(compiled on Jul 8 2011) Info : auto-selecting first available session transport "jtag". Warning - assuming default core clock 4MHz! Flashing may fail if actual core clock is different. Info : Listening on port 4444 for telnet connections Info : Listening on port 6666 for tcl connections Then I decide to test using OpenOCD with a Versaloon-Link programmer that I have here and it worked like a charm: $ sudo openocd -f interface/vsllink.cfg -f target/lpc2378.cfg ![]() Then I found a comment saying that the board needs 9V power supply:īut that is strange because I was powering the board using USB cable and the PWR_SEL jumper correctly selected to position 3.Īnyway I found a 9V power-supply and used that, but again JLink failed to find it. I started to suspect that I bought a damage board. Resetting via Reset pin and trying again. Initially I tried to use Segger J-Link to detect the processor, but without luck: J-Link>conįailed to identify target. I decided to buy an Olimex LPC2378-STK that I found on eBay because this is the first board I ran NuttX. ![]()
