2010-12-24 06:03:50     BF527 Alternate UART Console and Internal USB HC issues

Hi,

 

I am working with 2009R1-RC1 distribution and BF527 rev0.2 based custom board.

 

The debug console is connected to the UART1TXA and UART1RXA

 

PG12/DMAR1/UART1TXA/HOST_ACK

 

PG13/DMAR0/UART1RXA/HOST_ADDR/TACI2

 

after building the image when i load and run uImage i get the below error.

 

bfin-gpio: GPIO 29 is already reserved as Peripheral by bfin-uart !

Failed ro request USB_VRSEL GPIO_29

musb_hdrc musb_hdrc.0: musb_init_controller failed with status -19

 

Our project requires Alternate uart for debug console purpose and USB Internal host.

 

how to resolve these problems?,

make sure you configured the USB_VRSEL GPIO correctly in your board resources so that it matches your hardware

Dear Mike,

 

Thank you, In my current working hw, a direct +5v is applied to the device connected to the USB host.

 

By commenting out the gpio_pg13 operations in blackfin.c file in musb folder will solve my problem?

 

-Sreedhar.
