Hi ,
The RM57L843 is little endien and TMS570LC4357 is Big Endien controller while migrating from TMS570LC4357 to RM48L843 what all code porting needs to be done .
Are RM57L843 and TMS570LC4357: CRC Algorithm for 64BIT POLYNOMIAL SAME ?
Hi,
RM57L843 and TMS570LC4357 use the same CRC Algorithm.
The PSA_SIGREGL is for the lower 32-bit data, and PSA_SIGREGH is for the upper 32-bit data.
uint32 data[2]=(0x01234567, 0x89abcdef} --> PSA_SIGREGL = 0x01234567; and PSA_SIGREGH = 0x89abcdef;
On TMS570 big-endian device, if data=0x89abcdef01234567, the 0x01234567 is placed onto upper address, and 0x89abcdef is placed onto lower address, this means look like data[0]=0x89abcdef, and data[1]=0x01234567. for this case, we need to swap the upper and lower word.
