File format

The file consists out of a 0x200 big header (though the actual header is only 0x30 bytes, the rest is zerofilled), plus data whose size is indicated in the header.

Header

Offset Size Description
0x0 0x4 Magic "CCAL"
0x4 0x4 Version
0x8 0x4 Data size, always 0x7D0
0xC 0x2? ???
0xE 0x2 Bitmask of successful Aging tests
0x10 0x20 On devunits and if 0x1FF81006 is 3 or 4 or 7 or 8 or 9 then SHA256,

otherwise HMACSHA256 signature of the data section

0x30 0x1D0 Zerofilled, padding for the 512byte block size

Reading

If 0x1FF81006 is 3 or 4 or 7 or 8 or 9 then the callibration data is read from the EEPROM using the i2c:EEP service command 0x001000C0, using offset 0x000 for HWCAL0, and offset 0x800 for HWCAL1. Otherwise attempt is made to read CTRNAND:/ro/sys/HWCAL(0|1).dat instead.
