I wants to write an OBDS test file to communicate to a register of a chip(MAX232) which is connected to the UART of the main board.(imx6qSabre SD)

I am a beginner in this.

Waiting for your support.

Divya

Hi Divya

please look at i.MX6 SDK (OBDS tests)

i.MX 6Series Platform SDK : Bare-metal SDK

Best regards

Am following the same OBDS tests. But in that I couldn’t find a test app which covers my requirement.

MAX232 is just converter and there is no need for its programming.

All SDK Sabre-SD uart1 communication is done through FT232.

Its drivers located at: http://www.ftdichip.com/Products/ICs/FT232R.htm

Dear Igor,

the problem is actually in my two other modules like Bluetooth and Zigbee is connected.

I wants to confirm whether the Chips are working at OBDS level.

These two modules are connected through UART.

How can I ensure these chips are working?

I thought through UART by reading any register value of the chips will ensure that they are working

Waiting for your reply.

Hi Divya

you can use example in ..uart/src/imx_uart.c

as starting point. Then please check datasheets

Bluetooth and Zigbee modules, what protocol is required

for communication with them.

Best regards

Dear Igor

II have written one register read of A chip through i2c.

In that there are methods for accepting register address and chip addresses.

Like that is there any option in imx_uart.c
