Follow-ups

 

--- Bob Liu                                                  2010-08-25 00:24:55

fixed.

1. must run ppifcd-test on the modified BF533-STAMP board which use PF4 for

i2c-gpio.

2. change uclinux-dist/linux-2.6.x/arch/blackfin/mach-bf533/boards/stamp.c to

use PF4 also:

static struct i2c_gpio_platform_data i2c_gpio_data = {

         .sda_pin                = GPIO_PF2,

         //.scl_pin              = GPIO_PF3,

         .scl_pin                = GPIO_PF4,

         .sda_is_open_drain      = 0,

         .scl_is_open_drain      = 0,

         .udelay                 = 40,

};

 

3. always enable pack mode on bf533 else ppi will overflow :

./ppifcd_test -p 1 -b  533 -c3

 

Thanks for Michael's help.

yes, i modified the stamp.c file according the up description and rebuild kernel

.Then test it again with pack mode and found now is good.

So i closed the bug.

thank you Bob and Michael.
