Known Issues scarthgap.TQ.ARM.BSP.0006
- Default setting for
fdt_file in u-boot does not match older linux kernel
naming scheme. Current naming scheme is <cpu>-<som>-<baseboard>[-feature].dtb,
old scheme was <cpu>-<baseboard>[-feature].dtb.
See Build Artifacts for complete list of supported Device Tree files
- CAN
- CAN FD is only supported on MB-SMARC-2 up to 1MBit/s (system limitation)
- USB
- Port USB3 (X3 on MB-SMARC-2) is host only. Do only use a matching adapter
on MB-SMARC-2
- U-Boot: USB 3.0 port does not initialize USB 2.0 subsystem after USB reset
- Linux: overcurrent with some USB Sticks on MB-SMARC-2
- FlexSPI
- erase of ranges >= 16 MB fails under linux
- 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 all chip-selects are configured as GPIO
- 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.
