Lpc2000

Hi all,

I wanted to confirm the following operation of the LPC2124 on bootup.

1. The current Philips LPC2124 bootloader is Philips proprietary
- Please confirm

2. Bootloader operation
- Can you please confirm my interpretation of the power on reset and
bootloader action (This is what I have interpreted from the LPC2124
User Manual)

-Bootloader lives in the highest part of flash memory (8k size)
-On Reset.... The bootloader is remapped to the top of a 2Gbyte boundary
-64 bytes of the bootloader vectors are mapped in to 0x00000000 to
0x0000003f (the original interupt vectors).
-The bootloader is always mapped in to the same location (top of
2Gbyte) so, execution of bootloader address is always fixed.
-LPC2124 executes the  first instruction at 0x00000000 jumps to a
fixed address in the remapped 8k bootloader at the top of 2Gbyte.
-bootloader code executes and looks for a low on P0.14.
. ..... etc.... then follow the bootloader flow charts in the user
manuals.

3. Please confirm the bootloader s/w checks the status of P0.14 and is
not a fixed as a hardware test.


Does my executive summary of the start up of the boot loader seem
feasable?


Thanks.
