Part Number: PROCESSOR-SDK-AM65X
Hello,
In TI Linux SDK v05.03, which included the v4.14.79 kernel, we use MAIN_UART0 to communicate with a Bluetooth device. In this release, we could not communicate with this Bluetooth device until DMA was disabled for MAIN_UART0. We did so by adding the following to the main_uart0 node in the device tree:
/delete-property/ dmas; /delete-property/ dma-names;
When porting to TI Linux SDK v06.xx, this workaround no longer works for enabling communication with the Bluetooth device. We've tried both v06 TI SDK Linux kernel versions to no success.
Is it possible to disable DMAs in the same fashion as in the v4.14 kernel? Any suggestions on what to try or investigate would be appreciated.
Thanks,
Matt McKee
