Can somebody provide a working Vybrid DSPI sample code for any SPI chip under Timesys Linux ?

Respected Colleagues and Bruno Castelucci

 

I have made modifications for Phytec Vybrid Cosmic+ Board to the board-pcl052.c file in the way that Bruno Castelucci did in the board-pcm052.c file (Discussion SPI Driver on Linux Side).

 

Test from the shell like Bruno's with modeprobe spi_mvf_dspi returned:

 

# modprobe spi_mvf_dspi

DSPI: Coldfire master initialized

#

 

Does it mean that DSPI is correctly initialized? How can I trace it further? I see that Bruno got bunch of lines as a trace report.

 

So, can somebody attach a working example code for any SPI chip (EEPROM, FLASH, RTC, etc.) for Vybrid VF61 under Timesys Linux to make test on some real hardware chip.

 

This will help a lot for further development.

 

File with DSPI modifications for Phytec Cosmic+ Board is attached.

 

Thanks in advance.

 

With best regards,
