Hello, I have a embedded Linux product to develop, and it seem's that
the TS7400 board is perfect for me !
But I need some other fonctionnality :
- Another ethernet link
- 2 RS232 and 1 RS485
- Some isolated input
- Some relay output
- Eeprom to store product parameters (I want to have a read only
filesystem)
- Microphone input
- Speaker output
It seem's that I have everything I need on the 26 and 40 pin header :
- USB to add an ethernet link, with a RTL8150L for exemple
- 3 TTL RS232 for my 2 RS232 link and my RS485 link (with Tx enable)
- GPIO for isolated input and relay output
- SPI to store product parameters in external eeprom
- AC'97 interface to connect an audio codec and manage the microphone
and the speaker.
I want to now if someone has already used an external codec to have
audio fonctionnality, the codec used, and if the AC'97 audio driver
already exist for the EP9302.
For the USB / ethernet link, I think that driver already exist in the
kernel for the RTL8150L ?
Best Regards,
Cyril HAENEL
