  • TQMLS1088A: software reset or reboot always boots from QSPI when the flash contains a valid boot image.
  • TQMLS1088A: Suspend to RAM not supported.
  • SMMU bypass is required
  • MBLS10xxA: Interrupt of GPIO expander D57 (IRQ2) is permanently asserted because CLKO from CAN controller (D60) generates continuously interrupts on input of GPIO expander
    • There is no support for masking interrupts on the GPIO expander
    • This also affects the shared interrupts of D58 and D59 GPIO expander
    • Therefore the IRQ of GPIO expander is unsed
  • CAN-FD controller (D60) is not accessible using SPI
  • USB 3.0 Type-C (X16) is host-only
  • RS-485 (X23): linux,rs485-enabled-at-boot-time property must not be set
  • In BSP, suspend to disk is not supported, despite CONFIG_HIBERNATION being compiled into the kernel.
