Can M40 use ADMA_UART3 directly?

tiebing_guo — Wed, 08 May 2019 09:11:42 GMT

Dear Sirs

We are using android_p9.0.0_1.0.2-auto-beta release on IMX8QXP MEK board.

As the IMX8DQXPRM.pdf doc 12.5 shows the M40 LPUART supports to CTS&RTS for HW stream control.

But I can't find M4_UART0 CTS or RTS define in the M40 SDK, could you please guide us where is it ? and is there any demo code about it ?

On the IMX8QXP MEK board , only UART3's CTS&RTS pin are used as CTS、RTS function for BT UART,

is it possible the M40 to use the UART3 port directly in some situation? Such as M40 to communicate with BT chip before A Core launch.

Thank you very much~

Hi,

The i.MX8QXP is still on preproduction, so, no additional information/support could be provided yet. In case of having doubts, please refer with your Sales/FAE.

Hope this will be useful for you.
Best regards!
