Some board vendors actually changed the loader to expect the chip to come up in 4-address-mode and flipped the ADP bit in the flash chip's configuration register which makes it come up in 4-address-mode. Hence it doesn't make sense to avoid switching to 4-address-mode on those boards but the opposite as otherwise reboot hangs eg. on the WrtNode2 boards. Fix this by checking the ADP register and only using SPI_NOR_4B_READ_OP on chips which have ADP==0 (come up in 3-byte mode). See also datasheet section 7.1.11 Power Up Address Mode (ADP) Fixes: |
