Why do error occur after the programming is completed using E10A-USB?

Latest Updated:07/24/2008


When programming the flash memory in the Writing Flash Memory mode with the E10A-USB emulator, after the programming is completed and I click OK on the [Restart or Exit] screen that appears, I get the following error: [Key code error!].
I checked the Flash memory and the program had not been successfully written to the memory.


This is most likely caused by the selection of [Reset CPU after download module] in the [Debug settings], which should not be selected (no check) when using the Writing Flash Memory Mode.
To make sure [CPU reset after download] is not selected, go to the menu and select [Debug], then [Debug settings]. Make sure [Reset CPU after download module] is not selected (not checked) in the [Debug settings] option screen.
