We're suspecting flash SPI or DDR2 read/write corruption.
and we're looking for help to check the DDR2 config
we're using this as a reference
the interesting fields we found, but still looking for guidance on what to tweek where:
IBANK_POS, DDRDRIVE1, BOOTUNLOCK, DDRDRIVE0, TIMING_UNLOCK, LPMODEN, MCLKSTOP_EN, SR_PD, T_ODT, EXT_STRBEN, PWRDNEN.
