Did you mean you want two sound card instances in a system?

sound/blackfin/ad73322.c is a case for how to implement two sound card instances.

but this code is under ALSA framework,and ASOC framework just introduced this capability rencently.

Cliff,

Yes, I want 2 sound card instances, but found no ad73322.c, I am using the SVN 8920 kernel.

BTW, why the /dev/sport0/1 can't be accessed in SVN 8920 kernel, here is the error message,

root:/> cat audio_pcm > /dev/sport0

peripheral_request: Peripheral 25 function 0 is already reserved by bfin-uart !

bfin_sport: requesting peripherals failed

sh: can't open '/dev/sport0': Device or resource busy

ad73322.c driver is now a patch in SVN trunk. Please find it under uClinux-dist/bfin_patch/ad73322_patch/

As the log said, your UART driver shares the peripheral PINs with SPORT0 on your board.

Sonic Zhang,

I can make the /dev/sport0 runs well now, but /dev/sport1 still has that problem,

root:/mnt> cat audio > /dev/sport1

tcr1:0x3602, tcr2:0x20f, rcr1:0x400, rcr2:0xf

mcmc1:0x0, mcmc2:0x0

peripheral_request: Peripheral 37 function 0 is already reserved by UNKNOWN !

bfin_sport: requesting peripherals failed

sh: can't open '/dev/sport1': Device or resource busy

I check the /proc/gpio

root:/proc> cat gpio

GPIO_5: gpio-irq76 GPIO INPUT

GPIO_6: UNKNOWN GPIO INPUT

GPIO_7: UNKNOWN GPIO INPUT

GPIO_25: bfin-uart Peripheral

GPIO_26: bfin-uart Peripheral

GPIO_30: bfin-spi Peripheral

GPIO_31: m25p80 Peripheral

GPIO_37: UNKNOWN Peripheral

GPIO_38: bfin-uart Peripheral

GPIO_39: bfin-uart Peripheral

root:/proc>

I am using BF512, GPIO_37 is PH5, #define GPIO_PH5 37

and here is my platform_device, seems no device using PH5

static struct platform_device *stamp_devices[] __initdata = {

&rtc_device,

&bfin_spi0_device,

&bfin_uart0_device,

&bfin_uart1_device,

&i2c_bfin_twi_device,

&bfin_isp1760_device,

&ezbrd_flash_device,

};

How to check which device is using PH5?

The devices I am using now are rtc_device, bfin_spi0_device, bfin_uart0_device, bfin_uart1_device, i2c_bfin_twi_device, bfin_isp1760_device, ezbrd_flash_device, and I 've check all these code, none of them uses PH5. Actually, I did not modify any code check out from SVN.

PH5 is either PTP external CLK used by ethernet driver or ARDY( Asynchronous memory ready response) used by NOR flash driver. Please check if you enabled either in your kernel.

Please refer to the bf518 HRM for details.

every Blackfin driver should be requesting pins with descriptions. edit arch/blackfin/kernel/bfin_gpio.c and delete every "if (system_state == SYSTEM_BOOTING)" line so that you get a dump_stack() whenever a collision is detected.

you need to be using the latest svn trunk, not random versions

disable the SPI driver to see if it makes a difference, and display the value of is_reserved(peri, GPIO_PH5, 1) in your printk to make sure it is always 0.

After I disable ISP176x driver, the /dev/sport1 can work, but I check the code of ISP176x, can't find some code that holds GPIO_PH5, How can I use ISP176x and /dev/sport1 in the same time?

Without using /dev/sport1 ISP1761 can work correctly without using ARDY pin.

The last uclinux I used is version 8939, I checked out to version 8939, it still works. It seems the problem was caused by USB HOST driver, if I disable the USB HOST driver(ISP1761), version 8988 can work.
