[pocket-linux] Problem Chapter 3: RAMDISK: incomplete write (-28!= 32768) 4194304

[Eric Wanchic]

I believe I've pinpointed the solution to this particular error. Since the
Kernel was built was a RAM disk of 4096, then the other items previous
mentioned NEED to have that 4096 setting set, otherwise I assume since the
kernel is only expecting 4096 bytes and when it sees more (around 64000 in
this case), that the "compressed image" was not written correctly specifing
the "incomplete write."

See Below (solution response from David Horton):

Hense if your following the directions in v.3, you probably shouldn't be
getting this error (^_^).

Thanks Dave for your help!


* Note I'm still having issues, but not relating to this "particular"
problem anymore. Hense I'll be starting a new Thread.
