C161O, AMD AM29F002(N)BB 256K x 8 flash from 0x0 to 0x3FFFF, Cypress 128K RAM from 0x80000 to 0x9FFFF. 8-bit, non-mux bus at 16 MHz. The simplest program erases the sector at 0x8000, writes to it, then goes into a loop. When built under uVision 1, the target operates as expected. When built under uVision 2, the target erases the sector, but fails to write to it. Has anyone used C161, uVision2, and flash operations successfully?
