Flash Programming

Ton,

I am using cyclone I. I am not a FPGA guy.

check this out:

The line of *.flash file generated by the Nios II IDE says: "S32500000000140084003A48011004F8BF1016FDBF0034804000140840083A6800080000000010"

i tried to read back the same file from nios2 programmer using

nios2-flash-programmer --base=0x02000000 --read read_flash.txt

and its reads as

"S1230000140084003A48011004F8BF1016FDBF0034804000140840083A6800080000000012"

The difference i see is S1230000 and rest of the packets seems is ok.

This is the extract of the working code.( if i use the flash programmer.)

When i read by (*.flash file) nios 2 programmer it says

"S12300203030383430303341343830313130303446384246313031364644424630303334E3"

if you carefully observe here, S1230020 is ok, but then 533030 is nothing but ASCII values.

I think i got the problem,

I am sending the packets thru RS232 and saving it in a large buffer inside my code and then i am using the Flash API to download it into flash, when i do this , its not stored as HEX values instead its stored in equvivalent ASCII value.

For eg: if original (*.flash) is 0x06 then my code stores it as 0x36.

Any idea how i can download in proper HEX format?
