Hi,

From the manual, it stated that whenever the ARM Evaluator 7T is power up, the first program that it will execute is the Bootstrap Loader (BSL) located at memory location 0x1800000. BSL allow us to program the flash where itself is also residing at. Thus, the only flash location we could use is from 0x1820000 onwards.

For example, if I had wrote a program flashing the onboard LEDs, how do I get it running whenever I power up the board ?

Do I have to replace the BSL with my own application code which means erasing the BSL from 0x1800000 ?

And if I have to erase the BSL from 0x1800000, does that mean I could no longer use BSL to re-program the flash ?

Thanks.

Have a ncie day

Best Regards
