Hi, I am trying to convert my device to read EEPROM and precal through NVMEM but encountered a problem with precal size. Based on documentation and 19a954e, set the precal size to 54K + 16 + 102K = 159760 but I got a warning saying it failed to load precal and the size is 200720. Added some debug line for the precal sizes I got: mt798x-wmac 18000000.wifi: group size=96272 mt798x-wmac 18000000.wifi: dpd size=104448 mt798x-wmac 18000000.wifi: precal size=200720 mt7981 is using 2.4G + 6G cal group size but why? Then I took a look at the vendor driver and it's using 2.4G + 5G + 6G cal group size which looks even weirder. So which one is the correct size? I assume the correct size should be the same as the vendor driver but I might be wrong. Best regards, Zhi-Jun
