Problem connecting Kinetis FlashTool to UART

Hi all,

I am using the kboot v2 in order to update the KV31F uC firmware for a over-the-air project. I have already updated the firmware using the openSDA connection successfully, but when I try to do it via a USB-Serial converter(using pins PTB16 and PTB17) only "connection failed" errors appears to me. I have already tested with more than one converter so this is not the problem. How can I manage to do it using the UART ports directly?

Besides, after doing it I would like to update the firmware using another device and not the FlashTool, but I have no idea how to do it. Do you guys have any hints to give me??

 

Thanks in advance
