ADuCM4050 firmware download .

Hi, 

I am using a custom made HW. 

My goal is to use the CrossCore Serial Flash Programmer to download my firmware  to the HW. 

The problem is that as far as i understand for using the boot kernel i have download my firmware using UART0. 

On my HW UART0 is not available, I am wondering is there a chance to download the  firmware using UART1? 

Can i make an application that mimics the boot kernel behavior but works with UART1? Would you have the code of the boot kernel available?  

Thanks a lot 

Dani
