Lpc2000

Sören, I don't know it this helps, but with KEIL ULINK, when cycling power
or doing a hard reset from the IDE, execution starts and runs for a while
until the ULINK (Keil's JTAG interface) stops the core. This takes about 0.3
seconds. I put a 0.5 seconds busy loop in the startup code in order to
prevent this from causing damage to what I have in RAM.

Subject: [lpc2000] LPC2132 RAM corruption

Hello,

 

I would like to ask the people of this forum if anyone has experienced
problems with RAM being overwritten following a power cycle of the LPC2132.
I'm using GNU ARM gdb and a Chameleon POD with OCDRemote 2.12.

If I cycle power, download code with arm-elf-gdb ('load'), the code is
corrupted when I start executing. The corruption causes my code to crash. 

If I cycle power, download the with gdb and executed until crash, then
re-load to RAM (without power cycle) and start again, the program works
fine!

 

Any help / suggestions would be greatly appreciated.

 

Thanks in advance

Søren Madsen
