AM3358: UART RTS flow control

Genius 5820 points

Part Number: AM3358

Hi,

I'm currently using UART2 to transmit/receive data which works fine. Now for one specific application the RTS signal is needed too (which I found at U2/UART2_RTSN) but it seems I do not get it working in my bare metal application. What I have done so far:

  • pin-muxing, set CONTROL_PADCONF_LCD_DATA9 (0x44E108C4) to IEN|OFF|MODE6 (0x1A)
  • while UART config mode is enabled (REG_CONFIG_MODE_B = 0x00BF = set), configure UART2 for AutoRTS by setting AUTO_RTS_EN in register UART_EFR (set bit 0x00000040 in address 0x48024008)

So...did I miss something? Is there anything else which needs to be configured in order to use AutoRTS?

Thanks :-)
