I need to write 128 bytes of programm parameters into flash memory of the LPC933. Does any one no how to acomplish this function?
There are several ways depending on what it is you are trying to do.
The simplist is to hand create a hex file and program it into the device. This is good if the parameters are always the same for all devices.
If you want to do this every time along with a hex file containing your application or the data changes, then you can create a Just In Time module to do that, even inserting constantly changing serial numbers.
If this is more for storing non volatile data as your application executes, then you can use the IAP interface from your application to read and write flash memory.
