Hi Sergei ,
I fixed the previous problem however redboot stiil does not
work.
My board only has 256*16k external ram so I changed the
linker script ot reflect this (target.ld and the rom.ldi file
I have edited the hal_platform_setup registers BCFG0,1
and PINSEL2 for my board, removed ethernet setup as my
board does not have ethernet (BCFG2)
I have edited the mlt_arm_lpc2xxxxolpce2294_rom.h
for my ram size
I have changed the clock and pll multiplier using the
configtool for my board
Are there any other changes that I need to make?

Hello Miklos,
at first, I desire to ask you, Are you able to run any eCos application
(no RedBoot yet) in ROM with your own HAL? I.e., are those minimal
(hal/infra) eCos tests able to run in ROM?
Try it in bash:
<pre>
ecosconfig new <your target name> minimal
cat >minrom.ecm<<__eof
cdl_component CYG_HAL_STARTUP {user_value ROM};
__eof
ecosconfig import minrom.ecm
ecosconfig resolve
ecosconfig tree
make
make tests
</pre>
There shoud be 4 tests (it's main is to check HAL basics)
<pre>
install/tests/hal/
`-- common
`-- current
`-- tests
|-- basic
|-- cache
|-- context
`-- intr
</pre>
Burn in ROM test by test and view it's output in minicom/hyperterm
(38440,n,8,1). Possible, you will be need in other output format (they
are ELF images), you can get another formats with objcopy utility. If
you will see normal outputs, therefore your HAL is okay and time to port
RedBoot. If you won't see (there isn't time to RedBoot there), dig then
in the hal_platform_setup.h, and your platform mlt files, certainly.
