Code to load a LPC1114 over tx/rx. I have only tested with a 1114 chip but it should work with other LPC uControllers

okano | 26:a63e73885b21 | 8 | * This program programs MCU flash memory through UART. It uses |
okano | 14:a7b9f74fb856 | 9 | * "In-System Programming (ISP)" interface in target MCU (NXP LPC micro- |
okano | 14:a7b9f74fb856 | 10 | * controllers). |
okano | 26:a63e73885b21 | 11 | * |
okano | 26:a63e73885b21 | 12 | * The ISP is done by PC and serial cable normally. The ISP protocol is |
okano | 14:a7b9f74fb856 | 13 | * executed software on a PC. The software reads a data file and transfers |
okano | 26:a63e73885b21 | 14 | * the data with the ISP protocol. |
okano | 26:a63e73885b21 | 15 | * This program does same process of that. The mbed perform the function like |
okano | 14:a7b9f74fb856 | 16 | * "FlashMagic" and "lpc21isp". |
okano | 26:a63e73885b21 | 17 | * (This program not just copies the binary but also insert 4 byte checksum at |
okano | 14:a7b9f74fb856 | 18 | * address 0x1C.) |
okano | 26:a63e73885b21 | 19 | * |
okano | 26:a63e73885b21 | 20 | * This program currently supports LPC1114(LPC1114FN28/102 - DIP28-ARM) and |
okano | 14:a7b9f74fb856 | 21 | * LPC810(LPC810M021FN8 - DIP8-ARM). |
