## Know Issues

### All Kernels

- SDcard High Speed timing have compatibility issue with some brands.

    **Temporary workaround :** Disable UHS option/support.

- During SATA heavy load, accessing SPI NOR Flash will generate ATA errors.

    **Temporary workaround :** Disable SPI NOR flash.

### Legacy Kernel (4.4)

- PWM-FAN driver not working.

    **Temporary workaround :** Use GPIO-FAN driver, only 2 speeds supported (low or full speed).

### Legacy Kernel (4.14)

- DVFS doesn't use correct CPU freq range (666 - 1332Mhz instead of 800-1600MHz).
