Is their a guide somewhere to explain hex offsets
I want to write a 16k vn v8 file to the nvram to test it what offset do i use
Writing bins hex offsets
Re: Writing bins hex offsets
16k = 16384 bytes = 4000 hex
32k = 32768 bytes = 8000 hex
64k = 65536 bytes = 10000 hex
128k = 131072 bytes = 20000 hex
you just have to remember to always put the file at the end of the chip. eg: a 64k chip is 10000 hex long, you have to put it at the end, your 16k bin is 4000 hex long so you use offset C000.
(use windows calculator in Hex mode for calculating this stuff)
the nvram is 128k but split into two 64k halves by VL400's board, end of the lower half is 10000, to put it at the end of the lower half is 10000 - 4000 = C000. end of the upper half is hex 20000, minus your 4000 long bin is 1C000
32k = 32768 bytes = 8000 hex
64k = 65536 bytes = 10000 hex
128k = 131072 bytes = 20000 hex
