I build a new kernal today with the ADSP-SPIADC DRIVER and can sucessfully open "/dev/spi". However, simple write function calls produce no output at the SPI connector. Is there a switch setting that could cause this or do I need to run some the GPIO driver to set up the proper outputs?

Thanks,

Myrick

You should consider using the spidev user space driver.

Michael,

I am using the ADZS-BF537-Stamp board and the current release .... uClinux-dist-R1.1-1-RC3.

I think you are telling me to upgrade to the Beta version of the next release and install svidev. Is this correct?

Best Regards,

Myrick

I was wondering, is the BF537 supported by the old driver ADSP-SPIADC or is the driver only for BF533?

If I start over and use the spidev I have to modify the board file and I will need to know additional information in order to insert the conditional compilation directive for BF537. For example the BF533 has "#if defined(CONFIG_SPI_ADC_BF533) \ || defined(CONFIG_SPI_ADC_BF533_MODULE) {

.......modalias = ....

}

What is the conditional compilation directive for BF537?

Another comment...

I just reviewed the compiler options that I selected. They are:

1. Blackfin BF53x ADSP SPI ADC support

2. Blackfin BF53x Programmable Flags Driver

3. BlackfinBF5xx HW-Timers Driver
