When debugging an env fail due to too small a malloc pool, it was noted that the env write was 256k. But the device sector size is 1/2 that, as can be seen from "fli" output:
Bank # 1: CFI conformant flash (16 x 16) Size: 16 MB in 131 Sectors Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x1888 Erase timeout: 4096 ms, write timeout: 1 ms Buffer write timeout: 2 ms, buffer size: 64 bytes
Sector Start Addresses: FF000000 E RO FF020000 E RO FF040000 E RO FF060000 E RO FF080000 E RO FF0A0000 E RO FF0C0000 E RO FF0E0000 E RO FF100000 E RO FF120000 E RO [...] FFF00000 RO FFF20000 RO FFF40000 RO FFF60000 RO FFF80000 RO FFFA0000 RO FFFC0000 RO FFFE0000 E RO FFFE8000 RO FFFF0000 E RO FFFF8000 RO =>
The desired env sector is FFF40000->FFF60000, or 0x20000 in length, just after the 256k u-boot image which starts @ FFF00000.
