Here is the format of the numbers displayed on the error screen: | |||
BOOTROM 8046 | |||
ERRCODE: ffWWGGNN | |||
p3p2p1p0 p7p6p5p4 | |||
sd_softE sd_hardE | |||
* <code>ff</code>: sleep switch state (2==MCU sleep switch closed, 1==GPIO sleep switch closed (very bad if this happens), 0==sleep switch open) | |||
* <code>WW</code>: NVRAM (WiFi Flash) FIRM load error code | |||
* <code>GG</code>: ntrboot FIRM load error code | |||
* <code>NN</code>: NAND header (NCSD) load error code | |||
* <code>p<N></code>: NAND FIRM partition load error code. Note the order of the partitions in the error code! | |||
* <code>sd_softE</code>: software error (driver status bits, see one section lower) | |||
* <code>sd_hardE</code>: hardware error (SD controller status bits ? see one section lower) | |||
