I just bought 2 APU4c4's. The BIOS is very old (4.6.1)
I have followed the instructions on the site to flash it, using the TinyCore build ( https://pcengines.ch/howto.htm#bios ).
When I boot, all I get is memtest. If I try to bypass this by selecting TinyCore command line only, it hangs and does nothing.
I need to upgrade the BIOS in order to install PfSense, but am unable.
Does anyone have suggestions (link to tutorial would be very helpful.
