PSoC3 UART Bootloader error

I seem to get the example code breaking once the file is over a certain size.

   

I've uploaded small, 5kB projects via the bootloader without a problem, but once  I try to upload a larger file, 43kB, the bootloading fails just after the half way mark. Bootloader_host_gui.exe doesn't crash, but doe provide an error, and provides an error when I retry, this happens almost instantly.

   

I'm using a custom PCB with an FTDI232 as a USB to UART chip. Windows 8 and 7 seem to have the same results.

   

Has anyone come in contact with this or similar problem and is there a fix out there?

   

 

   

Thanks

Also, assuming you are in a 64 K part, your BL + stack must occupy

   

less than 21K.
