Well, it varies, alas. The firmware files can be bin or fw or other. Usually from /lib/firmware or a folder there BUT
can be in /usr/somewhere, this is not common
I don't know how the ko knows where to find the firmware
Firmware are for the wifi chip, are version and OS independent
It is 1 of them, there are 9 or 10 in total plus uboot and miniLoader and ?
Maybe I'm telling you something you already know, / in Android is only in mem,
loaded from the boot part, a gz cpio. Most of the folders in / (android ) are links to
the appropriate partition
 
I would guess that these are the ones you need, try copy them to lib/firmware/rtlwifi

Dmesg , if all is well, will give a message, ie  (dmesg |grep firmw)
usb 1-1.4.3: rtl8xxxu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin
for a usb dongle

Hi Balbes
Like nytoc, during boot it could not find rootfs
This is a H96Max+  ,, board labeled RK3328_8D4_V1.1
It has sv6501P wifi
About 1/2 the dtb don't even start to boot,
evb-android, both rock64, roc-cc, box-liantong
The rest, evb,  box,  box-z28, box-trn9, rockbox,
all have no mmc (ls /dev/block}
They will all boot with rootfs on usb stick
obviously uboot can read mmc, since uinitrd gets loaded (and kernel)
Once or twice, booted only with usb, I'm not sure which, maybe
box or rockbox
The next update, please compile ssv6051 module
I tried to strip the dtb out of resource.img, doesn't boot (mmcblk2p5)
Maybe there was more in that 8M partition, the dtb <60K
The android on it (8.1) is 4.4.140 (and rooted, that's how I got resource.img)
thanks for the work
--more--
There was no way I could make it go to maskrom with the button,
maybe there is a trick,, also could not do adb with usb,, lsusb never showed it
Had to use wireless adb
