# Generate correct GPT write command from TSV offsets

# From FlashLayout TSV:
# metadata1:  0x00080000
# metadata2:  0x00100000  
# fip-a:      0x00180000
# fip-b:      0x00580000
# u-boot-env: 0x00980000
# bootfs:     0x00A00000
# vendorfs:   0x14400000 (actually 0x04A00000 based on order)
# rootfs:     0x04A00000 (actually 0x14400000)
# userfs:     0xD4400000

# Convert byte offsets to LBA sectors (512 bytes each)
# And calculate sizes
