MSP430FG4619 programming problem

Hi,

I’ve start having problems programming my FG4619 as my code get bigger. When I try to program it with IAR (download and debug tool), IAR just bugs and I need to restart the program, sometimes a box popups saying that there was an error writing at address 0x2100 and then IAR bugs.

I am using the JTAG-tiny programmer from Olimex and a custom board with a FG4619. Have you ever experiment such problems? Thank you.
