Hi Hauke,
When the kernel gets uncompressed and is bigger than
BZ_TEXT_START - LOADADDR it overwrote the loader which was
currently uncompressing
it and made the board crash.
Currently, BZ_TEXT_START - LOADADDR = 0x80400000 - 0x80001000 =
3FF000 = 4190208 bytes
Today's trunk brcm47xx kernel is 4069124 bytes. So increasing the
address is actually
just a preventive countermeasure for future kernels.(?)
The change from 4.4 to 4.9, will add approximately 500 kbytes to the
kernel (assuming the increase will be similar as for ar71xx), so this
won't fit anymore. So this preventive measure may be needed sooner
than you think.
The WRT54GL CFEs seem to use a memory area about half the size of
your WRT54GS'
So I guess, the actual problem for the WRT54GL was that the stack
was smashed?
Once my compiling machine finishes your ar71xx with kernel 4.9, I'll
test this one here :-)
Happy to see, that this problem seems to be solved.
Regards,
P. Wassi
