hi all,

here is the crc calc algo:

Algorithm for CS1:
data from - 0x04
leight - 0x7C
CS calculated with Tricore internal CRC32 and low half word - CS1
Inicial value - block id


unsigned long crc_buffer(unsigned long crc, const unsigned long *p, unsigned long sz)
{
const unsigned long poly = 0xEDB88320;
unsigned long tmp1, tmp2;

while(sz--)
{
tmp1 = 0;
tmp2 = crc & poly;
for(int i = 0; i <=31; i++ )
tmp1 ^= ((tmp2 >> i) & 1);
crc = *p++ ^ ((crc << 1) | tmp1) ;
}
return crc;
}

Regards, G
