- USB
- U-Boot: USB 2.0 dual role port is limited to device mode for UUU / MFG use case
- U-Boot: USB 3.0 port does not initialize USB 2.0 subsystem after USB reset
- SPI: Hardware-controlled chipselects are not driven as expected
- Toggle after each Byte when using DMA
- Inbetween each
spi_transfer
- Use of GPIO controlled chip-selects instead is recommended
- By default chip-selects are configured as GPIO, if possible (see below)
- Note for MBa8Xx: The following pin cannot be configured as GPIO:
SPI3_CS1 on pad SPI3_CS1
** UBI / UBIFS images are enabled by default when using DISTRO=spaetzle[-nxp].
The generated rootfs size must not exceed the size defined by UBI_LEB_SIZE and
UBI_MAX_LEB_COUNT on machine level.
