Hardware Errata
DH Version 406-200:
Affected serial numbers:
1164AA KA11.0328 ...
11641A KA11.0328 ...
VCC_BAT errata:
Description: If VCC_BAT does not go down to 0V the processor may hang during a power-on cycle.
Workaround: Don't connect a battery or a gold cap to the VCC_BAT pin (pin 200) on the SODIMM-200 connector. In addition to that you can't buffer the date and time information.
SPI Flash errata:
Description: Boot from SPI Flash is not possible, because the wrong CS is connected to the serial flash memory.
Workaround: -
Affected serial numbers:
1164AA KA11.0328 ...
11641A KA11.0328 ...
51112...
50112...
UART1 CTS and RTS errata:
Description: DHCOM UART1_CTS and UART1_RTS inverted.
Workaround: Don't use hardware flow control.
SD interface wire length
The max. wire length from the SODIMM-200 connector to the SD Card Slot is 80mm (without buffer).
