Hi,
how to check size of the Interrupt Vector Table in LPC1768. I want to copy this table from flash to ram.
Regards
How to check? The datasheet mentions the size for the interrupt vector table. Or do you have any own code using part of the interrupt vector table region?
You are right. Now I found in the datasheet: "The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address space. The vector table should be located on a 256 word (1024 byte) boundary to insure alignment on LPC17xx family devices."
Thanks.
You didn't read everything in the user manual.
Look for example at figure 3 LPC17xx system memory map.
Does the vector table seem to be 1 kB large?
You may also look at table 51 and see if you find any vectors spanning the full kilobyte. 1kB has room for a lot of interrupt vectors, but the NVIC doesn't mention such a large number of vectors.
