The memory for the larger kernel does not stick between boots so I have
to do:
setenv bootargs_base \${bootargs_base} log_buf_len=2M
setenv bootcmd setenv bootargs \${bootargs_base} \${mtdparts}\; nand
read.e 0x32000000 kernel 0x300000\; bootm 0x32000000
saveenv
boot
at each boot but now the FR is taking forever to start with lines like:
[xxxx:yyyyyy] r5:.... r4:.....
[xxxx:yyyyyy] ..... kernel ....
[xxxx:yyyyyy] r5:.... r4:.....
so I can't get to the stuff below . .

Phil.
