USB with DMA can lead to deadlock or reboot

ID: COBALTSDK-978

Status: Open

First reported: 10.2.4.44

Fixed in: TBD

Description

The DMA support for the USB interface in the DA1470x is currently under development and should not been used. The usage of the DMA support for this interface can prevent the charger from starting. It can also trigger some assert in the USB driver.

Workaround

The workaround is to disable the DMA support when using the USB interface.

In the custom_config_<oqspi/ram>.h insert:

    #define dg_configUSB_DMA_SUPPORT                (0)
