Other Parts Discussed in Thread: AM3358

Hi,

I am using AM3358 Starter Kit(non os based). i have configured the UART0.

By using the USB to Serial Conversion i am getting serial data to and from the PC(HOST)

Through USB AB Connector.

UART0->USB to Serial->PC

UART0<-USB to Serial<-PC

Now i want to configure one more UART. for that what are

the possibilities avail. in the starter kit module i didn see any RS232 connector to connect to

the PC.

Thanks and Regards,

Hi Shanmugam,

I am afraid all other UART pins are occupied for other functions on the Starter Kit. You might be able to rig something by reworking the PCB and using external RS-232 level translator.

Found a possible solution. Check Starter Kit schematics page 3. UART2 TXD/RXD signals are pinmuxed on AM335X_SPI0_SCLK and AM335X_SPI0_D0, both of which are available on the Zigbee connector J11 (J11 isn't populated on the PCB). On the same connector you have also 3.3V and GND. You will still need an external RS-232 level translator.

As u told already , I have Configured the UART2 in am2335x.

But after the configuration of UART2 , UART0 also not working.

Can you assure whether the UART2 configuration will be possible.

i dont know whether it is a mistake on my side or unsupported

feature in the am335x. kindly check and tell me.

Thanks and Regards,

Shanmugam.S
