I was working with PN7462AU OTA referring the document "AN10995
LPC1100 secondary bootloader" application note.I tried porting the secondary bootloader code. I am able to jumb from seconday bootloader to application image area when both images are flashed to corresponding location manually. I have followed the 'interrupt redirection method' specified in the document.
Now I am working on image reception via UART in secondary bootloader side. Since interrupt redirection is there , I need to write this code without using interrupts. I am not able to find any sample code for uart sending and reception without interrupts .
Can anyone help me in this ?
