Sequence before, like in that case of MrPerfekt, reverting bytes will give you the number: 01 42Ĭonverting 142 into the decimal system you find that you need to cut 322 bytes (because 142h = 322d) Indeed, the guy from whom I learned this stuff, had to cut 322 bytes.Īlso, if you use the data03 file, please note that length must be calculated based on two bytes prepending the 01 01 00 1B sequence. If you extract incorrect number of bytes, the resulting 1B file will produce incorrect convolutuion in the FSC tool and hence the D1 error.įor example, if you see that in your generalPersistencyData_DiagnosticSWTController file you have different 4 bytes before the 01 01 00 1B, you must calculate the size based on this sequence in your file. This number of bytes, the length of the byte block that we need to extract, is an important thing. In other words, this means that to receive the correct 1B file, we must cut 319 bytes from the position 0x270 in the generalPersistencyData_DiagnosticSWTController file. Since the numbers are hexadecimal, the decimal value is 319 (because 13Fh = 319d). The proper order to compute the length will be: 00 00 01 3F That means we need to swap order of bytes to retrieve the correct order of bytes. For the CIC implementation we have the LE architecture.

This processor is based on RISC architecture and supports both LE (LittleEndian) and BE (BigEndian) byte sequence. The CIC IVI infotainment system is based on the Renesas SH7785 (former Hitachi) processor. These are the four bytes that define how many bytes you must cut from the generalPersistencyData_DiagnosticSWTController file to prepare the correct 1B hexadecimal file for using with the FSC tool.

For the data03 file the length of bytes to extract from the data03 file is indicated by 2 bytes that prepend the 01 01 00 1B sequence.įor example, if you open the generalPersistencyData_DiagnosticSWTController in a Hex editor (such as HxD) and jump to the offset 0x270, you may find the following sequence of bytes that prepend the 01 01 00 1B sequence: 3F 01 00 00 In the generalPersistencyData_DiagnosticSWTController file the length is indicated by 4 bytes that go before the 01 01 00 1B sequence of bytes. The length of bytes that you must extract from generalPersistencyData_DiagnosticSWTController or data03 files is indicated by the bytes prepending the 01 01 00 1B sequence.

However, there is a difference in how you compute the length of 1B sequence, depending on what file you have downloaded from the QNX computer via FTP service. The 01 01 00 1B sequence starts at the 0x270 offset. The generalPersistencyData_DiagnosticSWTController file can be found in /mnt/HBpersistence/normal/ on the QNX file system.Īlternatively, you may also use the debug data03 file, located in the /mnt/hbdebug/ folder. The block of bytes that you must extract from the generalPersistencyData_DiagnosticSWTController file starts with the following sequence of bytes: 01 01 00 1B

Someone knows how to solve “version after create () = 0xD1” error? Here are some tips of how to properly prepare 1B file for using in FSC code generator to avoid 0xD1 errors (“version after create () = 0xD1” ).
