#130320 - ISP and IAP Responding to: ???'s previous message |
ISP is not the same as IAP.... and your call to 0x1FF03 will not execute the ISP bootloader ( located at 0x1f00).
Do you understand the differences between ISP and IAP I stated in my previous reply? ISP Bootloader is the complete bootloader, IAP is a selection of functions to reprogram flash segments. IAP has "no direct" connection to the UART and hence no communications with Flash Magic. So, I think your code is incorrect... and NOW you can not get the LPC922 / 925 in to programmaning mode without using one of the 3 hardware modes (3pulse on reset for ISP, 7 pulses for ICP OR use a parralell programmer). This is the major problem with writing an incorrect NoTouch code routine.... there is no simple (non-hardware) program recovery. My advise is to purchase a MCB900 or LPC900 development system that will allow you to get to first base. Joe |
