Known Issues scarthgap.TQ.ARM.BSP.0008
- The OTG ID pin of the Micro-USB port (X10) is ignored in U-Boot. The mode of
the port is determined by the boot mode:
- When booting in USB host mode (from mass storage), the port uses host
mode. Access to the connected USB storage device is possible from the
U-Boot command line.
- For all other boot modes, the port will be in device mode. The "dfu"
command can be used to flash the boot media from a connected host.
- Some SD cards do not reset properly to their initial state when the system
is reset from U-Boot (using the
reset command or similar), resulting in the
subsequent boot to fail. If such issues are encountered, it is recommended to
switch to an SD card from a different manufacturer or try the workarounds
described in the
Processor SDK Linux for J722S documentation.
