Hi

I am trying to flash the code (str71xdemo_gp.axf) to ST Micro's evaluation board MB393B through ARM realView ICE ( JTAG Emulator). Processor: STR710FZ2T6. I want to use the embeded (internal) flash. During the time of flashing I have maintained the following boot settings: ( RAM MApped at 0h) BOOTEN:1 BOOT0:0 BOOT1:1 I could succesfully flash the code. Swicthing off the supply, I changed my boot configuration settings to USER mode ( Flash mapped at 0h) to run the program. BOOTEN:0 BOOT0:0 BOOT1:0 But I am not finding anything on the LCD Display. I am not in a position to findout whether the program is correctly booting from internal flash. Can anybody help me in giving the correct procedure( step-by-step) of flashing this code, all the necessry H/W settings to be maintained on the board. Also tell me Is this, the only file ( str71xdemo_gp.axf)I have to use for flashing or any other associated files are required along with this. If so please mention the same.

Hi

I have used this evaluation board for other purposes during my project development.The board is working fine. But during that time i was using the debugging environment. Now I am trying to flash the code. The board is not displaying anything. Let me try LCD.zip code. But Is it enough if I just flash the code present inside this zip folder (lcd.zip)? Or any other files required? What should be the boot configuration settings?

As you sugeested we used this file in debugging mode.

We were able to see some segments of the LCD blinking We could monitor Enable signal toggling at the LCD ( 6'th Pin). ( I think some portion of LCD has gone bad). Now in the second phase I flashed the same code. My expectation is to observe the same phenomenon on the LCD display. But I didnt see any blinking on the LCD screen which I observed in the previous experiment. Could you help me in this regard...
