Hi, I adapted the 'hello world' blink LED Assembler example for the LPC17xx to the ezSBC2 1374, originally from here:

ZIP archive is here:

(Choose 'File->Download' Google Drive viewer to get the ZIP file)
This ZIP also includes a quick and dirty C program that computes & inserts the required checksum at Reserved Vector 0x1C of your assembled .BIN image so the ezSBC2 USB firmware loader with accept the file.
