2010-01-22 14:46:49     bf526-ezbrd system boot fail with nand is enabled

Hi All,

 

first of all, this is my first thread in this forum so i'll try to provide all the info you'll need.

 

I'm compiling 2009.11-svn2200 distribution for a BF526-ezbrd, and i got the system working properly only if the NAND flash is disabled.

 

I enabled the nand command in the u-boot and i can get "nand info", "nand read" and so on working.

 

I enabled MTD and UBIFS support into kernel as described in:

 

  docs.blackfin.uclinux.org/doku.php?id=linux-kernel:ubifs&s[]=ubifs

 

The problem is that booting the system, my kernel recognize the 3 memories (NOR, SPI and NAND), but then it suddenly crashes. (attached there's the dump of the system crash)

 

Thank you very much in advance for your help.

 

Denis

you need to configure your kernel properly and read the error messages

 

peripheral_request: Peripheral 37 function 1 is already reserved by bf5xx-nand !

bfin_mii_bus bfin_mii_bus.0: Requesting peripherals failed! bfin_mii_bus: probe of bfin_mii_bus.0 failed with error -16

 

dont enable drivers with conflicting pin requirements

 

the NULL pointer after that is a bug, but irrelevant to the underlying issue.  we'll fix that.

Dear Mike,

 

thank you very much for your help, I did disabled network device driver and now the kernel boots properly.

 

Thanks again.
