1.8t checksum is bad??
« on: January 02, 2023, 05:56:56 AM »
I programmed my ECU today. I modified it because I wanted pops&bangs.
The car did not start after uploading. The entire program has been loaded.
Luckily, I was able to upload the ori file. Does anyone know what the problem is.
I use mps. Audi tt 1.8t 98.

if it can help...
ME7Sum (v1.1.2) [Management tool for Bosch ME7.x firmwares]
Inspiration from Andy Whittaker's tools and information.
Written by 360trev and nyet [BSD License Open Source].
Attempting to open firmware file 'POPS8N0906018AB.bin'
Step #1: Reading ROM info ..
Searching for EPK signature...OK
Searching for ECUID table...OK
EPK : '36/1/ME7.5/5/4019.00//F19u3/Dst02o///'
Part Number : '8N0906018AB '
Engine ID : '1.8L R4/5VT '
SW Version : '0002'
HW Number : '0261207027'
SW Number : '1037354503'
Step #2: Reading ROMSYS ..
Startup section: word[0x008000]+word[0x00FFFE]
@08038 Add=0x0000E5B3 CalcAdd=0x0000E5B3 ADD OK
All param page: word[0x010000]+word[0x01FFFE]
@01a896 Add=0x00971D CalcAdd=0x00971D ADD OK
Step #3: Finding CRC table(s) ..
Searching for CRC table(s)...OK
CRC table(s) OK
Step #4: Reading RSA signatures ..
Searching for RSA offset #0...missing
Searching for RSA offset #1...missing
Step #5: Reading Main Data CRC/Checksums ..
Searching for main data CRC pre block...missing
Searching for main data CRC/csum blocks...missing
Falling back to default 512k CRC blocks...OK
Searching for main data CRC offsets...OK
Searching for main data checksum offsets...missing
Main CRCs:
1) 0x010000-0x013FFF @6693c CRC: 03AA9D3E CalcCRC: 03AA9D3E CRC
2) 0x014300-0x017F67 @66942 CRC: 9FBCA63F CalcCRC: 9FBCA63F CRC
3) 0x018191-0x01FBFF @66948 CRC: 42380CD2 CalcCRC: 42380CD2 CRC
Step #6: ROMSYS Program Pages
Program pages: 8k page first+last in 0x0000-0xFFFF and 0x20000-0x7
@00803c Add=0x41CD80 CalcAdd=0x41CD80 ADD OK
Step #7: Reading Main Program Checksums ..
Searching for main program checksum..OK
ROM Checksum Block Offset Table @1bfcc [16 bytes]:
1) 0x000000-0x00FBFF CalcChk: 499CCE49
0x00FC00-0x01FFFF CalcChk: 3D3CD6F6 CalcCRC: DCEE4698 SKIPPED
2) 0x020000-0x07FFFF CalcChk: F9DF09E3
@7ffe0 Chk: F9DF09E3 CalcChk: F9DF09E3 OK (i)
Step #8: Reading Multipoint Checksum Blocks ..
Searching for multipoint block descriptor #1...OK
1) <14224> 0x024000-0x026567 Chk: 0AE61FD2 CalcChk: 0AE61FD2 OK
2) <14234> 0x014000-0x014243 Chk: 005FB53E CalcChk: 005FB53E OK (
3) <14244> 0xFFFFFFFF-0xFFFFFFFF END
Multipoint #1: [2 blocks x <16> = 32 bytes]
Searching for multipoint block descriptor #2...OK
1) <1fc00> 0x000000-0x003FFF Chk: 0FA0F5CF Boot: (whitelisted) OK
2) <1fc10> 0x004000-0x007FFF Chk: 0F4716B3 Boot: (whitelisted) OK
3) <1fc20> 0x000000-0x003FFF Chk: 0FA0F5CF CalcChk: 0FA0F5CF OK
..........
Multipoint #2: [34 blocks x <16> = 544 bytes]
Step #9: Looking for rechecks ..
*** Found 41 checksums in POPS8N0906018AB.bin
*** DONE! 0 error(s) in POPS8N0906018AB.bin! ***

Thanks for the help.
The error was in mpps.
Pops work but too hard for me.
