Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

Obtaining RK3066 boot ROM.

Here are my steps.

At first, I took a look to RK30xxLoader(L)_V1.18.bin. This file appears in update.img for my device. So, I unpacked update.img using rk29Kitchen.

strings on that file returns nothing interesting, so I assumed the file is crypted

NEC 78K0 Flash Vulnerability

Overview

The microcontroller that I studied was removed from a Volkswagen car radio manufactured by Delco (now Delphi). The chip had only Delco markings on the package. It was decapsulated and the markings "NEC D78F0831Y" were found on the die. I reverse engineered the device definition files for the NEC toolchain (RA78K0) and determined that the uPD78F0831Y is a subset of a documented chip, the uPD78F0833Y. The '833Y adds 3 more timers, extended I2C functionality, and adds registers that allow firmware running on the '833Y to reprogram the flash ("self-programming"). Otherwise, the '831Y and '833Y are the same.

The uPD78F0831Y uses the NEC 78K0 core. Note that NEC (now Renesas) produced a number of incompatible cores with similar names such as 78K0S and 78K
