Hello All,

I have compiled and loaded a custom kernel (uClinux-dist-2008R1-RC8) on to a BF561 but when it loads all I get is garbage. I was hoping maybe you all could point me in the right direction.

I selected 561 in the make menuconfig and everything compiles fine. I transfer over the uImage file via kermit and loadb.

Here is my proceedure on the 561.

erase 1:1-30

cp.b 0x1000000 0x20020000 <(file size+1) in HEX>

go 0x1000000

When it loads, I get the following output.

Image Name: Linux-2.6.22.18-ADI-2008R1-svn

Image Type: Blackfin Linux Kernel Image (gzip compressed)

Data Size: 3877868 Bytes = 3.7 MB

Load Address: 00001000

Entry Point: 00146000

Verifying Checksum ... OK

Uncompressing Kernel Image ... OK

Starting Kernel at = 146000

the two common errors which result in this are:

- improper baud rate

- improper kernel selection of processor/board/clock settings

Yea, I think you are correct.

I had Analog Devices -> 561 selected but my board is a Bluetechnix 561. I'll try that and see what happens.

My board (to the best of my knowledge) doesn't have an active ethernet port. How do I get the rootfs on to the 561 board? I assume it'll be something like loadb into 0x1000000. But then where do I cp.b it into memory?

you either use a kernel with a rootfs attached, or you put the rootfs into flash

Maybe I spoke incorrectly. How do I get all the "applications" (mplayer, vlc, etc) onto the device? I assume they aren't in the kernel image.
