- Help me please. How can I configure the data exchange with the Linux 3.2 kernel without using the Internet cable (com-port only)? Thank you.
- Good day!To make the connection between DSP / ARM cores on MityDSP-L138, can we use your MDK with a previously developed project in Studio Composer Studio on PSP and DSP / BIOS written in C (and not with C ++)?

Offhand our recommendation would be to utilize an HPS GPIO and have it configured in the GPIO controller as an interrupt.
Additionally it would be pertinent to know how long you expect power to persist after this interrupt ... - CS 05:14 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Power fail interrupt
- What more is there to say, really? We have a low voltage supervisor in our design and when the power is going to fail, we would like to take the necessary precautions before power is completely gone.

Could you describe the situation a bit more?
Thanks!

- Hello,
I own OMAP-L138F board and I am still new to this platform. Would you kindly inform me how can I set the board to read and send analog input ad output?
I am planning use integrate this board to a microwave radar.
