2009-08-06 07:44:05     How can I attach both spi mmc and another spi adc in 08r1.5?

Dear all,

 

     My hardware is bf561, kernel is 08r1.5

 

     As SPI support is dropped while spi_mmc enabled, how can I  control the ADC via SPI interface?

 

     Can I write Blackfin SPI bus directly at the same time?

 

    Thanks .

Is it possible that you move to 2009R1? The original spi_mmc driver has been replaced by mainline mmc_spi driver. And you can use the "spi_lock_bus()" functions if mmc_spi cannot share spi bus with you ADC properly.

 

If you insist on using 2008R1.5, you may set spi_mmc driver to use spi frame work (do not use spi bus directly).

Dear Li,

 

         Thanks for your kindly reply.

 

         I can move to 2009R1. How can I get the toolchains for 09R1? And can you tell me when the 09R1 will be formally released?

Please download and use 2009R1-RC10 toolchain:   blackfin.uclinux.org/gf/project/toolchain/frs/?action=FrsReleaseBrowse&frs_package_id=74

 

2009R1 will be release in one or two week. You can use 2009r1 release candidates. There are just bug fix - no major changes.
