Hi everyone, 

 

I'm using LPC1837 micro controller for some application development. This micro controller has on-chip flash memory of 1MB. 1MB is shared between two memory banks Bank A and  Bank B. each bank has 15 sectors 0-7 with 8kB size and 8-14 with 64kB size.  boot loader code resides from sector 0 to sector 8 in bank A. 

 

Now if i try to write  application code in the sector 9 or 10 in the bank A. it is hitting the hard fault handler. 

 

if the same application code in written in bank b any sector,  it works fine without and problem. 

i'm using IAP command to erase and write . 

 

can anyone please explain about this and also how to solve this ?
