kumar v (INDIA)
I am using BF527 EZKIT, I would like use PG5 and PG6 as SPI slave selects. I will be using the SVN trunk for my testing on the board.
In the platform file by making below changes:
.chip_select = 0x00,
.cs_gpio = GPIO_PG5
similarly for slave 2 by making .chip_select = 0x00 and .cs_gpio = GPIO_PG6 will I be able to access the SPI slaves from the drivers without any problem?
Because I read in the below tracker raised by Barry Song, that spi driver throws a error "chipselect 0 already in use":
Is this issue resolved in the latest trunk? I will be starting my testing very soon, your feedbacks will help.

Message: 83245 The issue is fixed on trunk.
You now would use:
.chip_select = GPIO_PG5 + MAX_CTRL_CS, /* GPIO controlled SSEL */
.cs_gpio does no longer exist.
