Hi, i am building a bootloader for lpc1788.

I know there is u-boot, but i have built a similar bootloader which reads the firmware via SD card for the lpc1769.

I have ported the code over to be used for lpc1788, however, i will get a hard fault error whenever i declare a large array for example

void main()
{
array buf[512];
debug_printf("test1");
}

just this code alone gives me hard fault error.... it seems that my configuration files are not setup properly, any hints???

i am using crossworks for arm ver 2.3

any help will be appreciated thank you.

Just two general notes:
- You may have not setup stack correctly
- You have no while(1); at end of main

Hi Jaybee

I'm about to do exactly the same thing (LPC1788 bootloading via SD Card). I would really appreciate any tips on how to get started. Can you tell me which bootloader you got for the LPC1769?

Thank you for your time.
