i've usde LPC2119 MCU on a self developed board. i used JTAG for flash download and it worked perfectly fine.
problem : I replaced LPC2119 by LPC2109 for the same application. Now the flash download through JTAG fails on the same board with LPC2109 MCU. The tool is able to identify the Device (i.e ARM7TDMI-S core) but the process dies abruptly as i try to download into MCU flash.
Error Message : error: flash download failed - ARM7TDMI
Message in output Window reads: Load "C:\\Keil\\ARM\\test project\\test.AXF" Full Chip Erase Failed!
Yes, I did verify. Both the chips require different flash algorithm. However, I used correct flash algorithm for corresponding chip.
