Hi John,
Please follow me to modify your code, I have test it on my side, all three color LED is working on my side.
unzip a new lpcopen code, add lpc_board_nxp_lpcxpresso_lpc1769 and lpc_chip_175x_6x project at first.
1. open lpcopen code: perph_blinky project
2. Modify the systick.c code like this:

SysTick_Config(SystemCoreClock / TICKRATE_HZ1);
/* LEDs toggle in interrupt handlers */
while (1) {
//__WFI();
}
return 0;
}
3. Build the code, and download it, run the code
You will find GREEN, BLUE,RED, are all working, you can debug the code.
Have a great day,
Kerry

Hi John Whitmore,
1. OM13085 hardware broken problem
From your picture, the PCB pad also broken, so, even you can't fix it by yourself.
I don't know where you buy it, if you buy it from the nxp website, please follow this link:
Returns and Warranty Information|NXP
Please fill it, just to do the return request.
2. OM13085 Get Started link
The link in the board card is the old one, now it is replaced by this link:
LPCXpresso board for LPC1769 with CMSIS DAP probe|NXP
3. LPC1769 sample code
LPC1769 don't have the SDK code, it just have the lpcopen code, you can open it with LPCXpresso IDE or MCUXPresso, IAR, MDK.
1) LPCXpresso IDE
2). LPC1769 LPCXpresso IDE & MCUXPresso IDE lpcopen code
https://www.nxp.com/downloads/en/software/lpcopen_2_10_lpcxpresso_nxp_lpcxpresso_1769.zip
3)LPC1769 IAR & MDK lpcopen code
https://www.nxp.com/downloads/en/software/lpcopen_2_10_keil_iar_nxp_lpcxpresso_1769.zip
You said, the MCUXPresso can't support the LPCopen code, but I have test it on my side, it works OK, but I am using windown 7 system, I don't have linux system.
This is the debug information, the board LED blinks Ok.
My PC is the windows system, I can't test the linux system on my side.
I think, maybe you can also try to download the LPCXpresso IDE linux version, and try the lpcopen code.
Wish it helps you!
Have a great day,
Kerry
