Re: [uracoli-devel] Wireless Bootloader Hex Error

[Brad Brooks]

Using the -O 0x1FFEF worked.  I used -O option because without using it, I would get an error message.


Thanks to everyone who replied,

Hi Brad,

What the script is doing is to attach a record at the end of flash containing address information. It is 16 Bytes long. The offset to use is FLASHEND - 16 Bytes, in case of ATmega128RFA1: 0x1FFFF-0x10 = 0x1FFEF

Using -O 0x1FFEF should work, or better: let the script calc as Jörg suggested.

As Brad Brooks wrote:

I create the wibohost hex file using the following:
D:\uracoli\uracoli-devel\install>python wibo/nodeaddr.py -B brooks128rfa1
-M atmega128rfa1 -c 17 -a 1 -A 0x001c2c00004c6000 -p 0xcafe -O 0x1ffff -f
bin/wibohost_brooks128rfa1.hex -o 0001.hex

If you are going to put the data at address 0x1FFFF, and the data
are (obviously) more than one byte long, this must overflow the
flash size.

Solution: don't use -O, and let the script calculate the correct
offset by itself.
