hi, i want to debug program in external ram, it is my set, but it doesn't work. keil platform. the external ram using bank1 ne3.
1. Optioin target ROM1 checked, start 0x68000000, size 0x80000, select startup RAM1 checked, start 0x68080000, size 0x20000
2. flash download RAM for algorithm start 0x68080000, size 0x2000
programming algorithm start 0x68000000, size 0x00080000
debug initialize file
