LPC1769 HardFault when using EthernetBootloader

[madid87]

Hello everyone,
I'm using an Ethernet bootloader and it works. I know this because I can successfully program the Blinky example and it runs. The problem comes
when I try to program my custom application. After the execute_user_code(); function is called I always get a HardFault handler.

I have made modifications to Target dialog tab by setting IROM1 start at 0x2000 and ticked the Linker tab with "Use Memory Layout from target dialog". Memory map file shows that
my code starts at address 0x2000.

Please help me. I don't know what to try next. I cannot find any difference between the provided Blinky example and my application and yet my application doesn't work.

Best regards.

There are two approaches I would try in this situation:

  - start stripping your project down bit by bit until it is the same as the blinky example

  - start building the blinky example up bit by bit until it is the same as your desired project

Makes sense, I will try it.
If you have any other idea of what might be wrong I would appreciate it.

I don't see any vector table offsetting being done, so I presume it's not needed?
