Likely some of your basic initialization is wrong or incomplete:
- Are cache(s) enabled?
- Is the memory system initialization correct (wait states)?
- Is the CPU clock tunable (and does it run at full speed)?
Also get the source code of the stock redboot for your board to see what
they have done.
Best,
Kurt

Subject: [ECOS] reboot is slow
hi
i have rebuilt redboot successfully (RAM and ROM versions), every thing
works fine but slow, very slow. the board is ap48 (a ubnt nanostation 5,
which i like to customize), it has a stock redboot wich runs much faster
than what i have built !!!
for example pinging the board (running stock redboot) replys in about 4
ms average while pinging with my redboot is about 30 ms.
decompressing a lzma image takes forever (10+ minutes) !!! the stock
redboot decompresses it under 5 seconds. running from ram or flash dose
not make that deference. loading files from tftp also very slow about 10
kBps
i took the code and patches from dd-wrt microredboot
more info about the broard:
cpu: mips 4kc 180 MHz
rom: 4 MB
ram: 16 MB
what can i do to figure out the root of the problem??? any help is
appreciated.
thanks in advance
regards
