Hi Michael, Probably I will have to write some separate code loader application, to be run in RAM. My software download scenario is as follows: 1. The CTL application runs normally and then it receives START_PROGRAM_DOWNLOAD command (through some proprietary serial protocol). 2. I presume that the command processor task will have to disable IRQ and FIQ interrupts (I use both of them), copy a ram runnable image of software loader application from flash to RAM, and start it. 3. Probably the loader application can be a CTL application too. It will respond only to software download part of the serial communication protocol. The reason, I want to run a CTL application for the download is that I want to use the same serial drivers and the same RS-422 Tx driver enable/disable timing mechanism, I use in the main application. Every time a RECEIVE_PROGRAM_RECORD command is received, it may call an IAP function to program the flash. 4. After the software download completes, an END_PROGRAM_DOWNLOAD command is received. On reception, the loader application will disable all interrupts, and reboot the LPC2106. I will be glad to have your remarks. In addition, if there is anybody on the board that already did IAP inside a CTL application and wants to share the experience, it may be of benefit to all the board members. Many thanks, Eli. --- In , Michael Johnson <mpj@r...> wrote: > Hi Eli, > > We ship the source code of the flash loader in the CrossWorks for ARM > distribution which could be a place to start.
