Wrong CS writing into file in Step 2 at Startup section (Addr @08038) #14

Hello and thanks for such a nice utility!

I faced an issue when ME7sum is writing wrong CS into file in Step 2 at Startup section (Addr 08038)

Usually we do not need to change Startup section in flash files - so no CS correction is needed there...
But I changed it accoding to my purposes and faced this issue.

For example:

Step #2: Reading ROMSYS ..
 Startup section: word[0x008000]+word[0x00FFFE]
 @08038 Add=0x00013AD3 CalcAdd=0x0000C8AD ** FIXED **
 All param page: word[0x010000]+word[0x01FFFE]
 @01bf66 Add=0x00971D CalcAdd=0x00971D  ADD OK

CS itself in this step is calculated correctly, it should be 0x00013AD3 (in flash D3 3A 01 00), but when the program writes data into file - it is D3 3A 00 00

And ofc all other CSs after this offset are notOK)

When I recheck CSs of already fixed file with ME7sum via ME7sum - it tells that 1 CS is notOK and trying to correct it once again... and again and again...

Solution:

I change the first fixed file via HEX editor (filling correct CS: D3 3A 01 00 in Addr 08038 manually) and save it.
After that I am running ME7sum again with my manually fixed file and fix all the rest CSs with it.

Profit! (Now the last correction is identical to WinOLS CS correction method)

It would be great if U fix this issue)
