Hi,
I want to use the I2C1 on logicpds OMAP-L138 SOM-M1 by the DSP core. On the ARM I use Linux (distribution provided by logicpd).
The I2C1 and the UART2 of the OMAP-L138 share the same pins. The UART2 is the default terminal of the linux system. Due to that I am concerned, that the Linux System will manipulate the I2C-pinmux-configuration to be UART2.
If I configure the pinmux of I2C1-pin to be I2C1 (instead of UART2) and set the default terminal of the Linux system to UART0 or UART1, is it possible to use the I2C1-port by the DSP?
I need this information for the decision which I2C to use in my layout. I suppose the linux distribution can be compiled with the desired pinmux-options, however I have no opportunity, to test this at the moment.
Kind regards
Andi
