tftp firmware upgrade with .trx?

Does anyone know if it is possible to use a .trx file with tftp?

 

I have installed a serial socket on my R7000 and that works fine. The tomato upgrade seems to require a .chk initial upgrade, but that appears to be an issue with the stock firmware. 

I was wondering if the CFE tftpd server can flash a .trx or if it too must use a .chk.
