I dont see any code that copies your main code to RAM first before it calls flash_write. So can someone explain how this works? </SPAN><BR /><BR /></BODY></HTML> Wed, 15 Jun 2016 19:41:25 GMT lpcware 2016-06-15T19:41:25Z Firmware upgrades https://community.nxp.com/t5/LPC-Microcontrollers/Firmware-upgrades/m-p/539715#M11927 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by Muis on Mon Jan 14 09:59:45 MST 2013</STRONG><BR /><SPAN>I always thought that for upgrading firmware a secondary bootloader was required, but when browsing the LPC11Uxx USB ROM examples, i saw an example application (USB_ROM_MSC_HID_DFU) that has DFU (Device upgradeable firmware) functionality, and just calls flash_write from your main program to overwrite the current firmware.
