Emisar D4V2 Flash Kit Instructions (Official How To)

LED Flashlights – General Info
192

Thanks once more TimMc for this quick and detailed answer. I will check the links you have mentionned.

This is precisely the next light I’m considering to buy, but only once/if it becomes available with a warmer, higher CRI LED.

I would also be able to upgrade it to Anduril 2 and future versions, hence my questions.

Some people have bought a SC31 Pro and then swapped the emitter with something nicer.

Tom E took some photos of inside the SC31 Pro head:

And how to remove the bezel:

It might be worth discussing on a Sofirn SC31 Pro thread too:

Hey Guys

How do I find out what the latest update contains? for e.g muggle mode issues being sorted out?

Thanks

It’s possible, but you’d need to remove the bezel with force and desolder some wires to poke the board down and get access to the MCU.

Sofirn haven’t made it easy to reflash the SC31 Pro.

Could someone confirm if my understanding is correct -

From the Flashlight Firmware Repository, if I want to get the latest firmware for Anduril I simply download the tarball for rev 490 (as of Nov 2020), using the ‘make’ command via Avrdude that will produce the most recent firmware as .hex files for FW3A, D4V2, KR4 etc?

I know it’s rather a newbie question, coding isn’t my background although I’m now a day into learning C in order to get my head around the code structure.

Thanks in advance.

199

I think the canonical way is to run `ToyKeeper/spaghetti-monster/anduril/build-all.sh`. It’ll produce one hex file per “cfg-” file in that same directory.

Thank you very much!

Haven’t updated my d4v2 since the muggle mode issue but thought it’s good to know what the latest updates are!

I guess all of Hank’s lights are ones you can use pogo pin with?

Thanks

Thanks Tim, I do follow the SC31 Pro thread now.

I'v seen this very successful achievement by SammysHP, but this is not within the newbie's reach.

So unless a dedicated easy-to-use flashing kit becomes available, I'll be waiting for a future version of the SC31 Pro, more upgrade-friendly as I suggested in a PM to Barry.

Hey guys, I have a D4V2 with the KR4 driver i bought straight from hank. I was wondering if you guys knew what settings i needed for a PC based update… and if an update came out in the last year? Do we still use the same drivers/software outlined in this thread?

204

Which LED option is installed on your D4v2 with KR4 driver?

205

Xp-l hi v3 I believe

206

So your D4v2 has XPL-Hi LED and the KR4 driver (5A CC constant-current + FET).

I believe the correct .hex file is either the

anduril.2020-07-08.emisar-d4v2.5.hex 2020-07-08 21:55 26K
or
anduril.2020-04-27.noctigon-kr4.hex 2020-04-27 19:21 26K

in the TK Anduril 1 firmware repository (URL: Index of /torches/fsm )

I think I’ve encountered an issue (strobes issue?) with the “2020-07-08.emisar-d4v2.5” so I used the “2020-04-27.noctigon-kr4” instead

Or use

anduril.2021-01-25.noctigon-kr4.hex 2021-01-25 00:06 26K

if Anduril 2 ( URL: Index of /torches/fsm/anduril2 )

207

How do I figure out the correct one between the two? I know it has the KR4 driver but is the D4V2ti. I’m assuming it goes by driver and not flashlight model?

208

D4v2 with XPL-Hi LED can use the FET version (ie. not the NoFET version).

The firmware goes by the driver, not exactly the flashlight model.

I think there was some previous discussion regarding the difference between D4v2.5 and KR4, which I can’t exactly remember (will need to search previous posts or other message threads here in BLF). Both mentioned hex files would be usable on the D4v2 with the KR4 driver… but one may have a few issues (can’t remember exactly though… should be minor issue only)

209

Hi all
I flashed anduril.2021-01-25.noctigon-kr4.hex on my D4V2 with XP-L HI V3 3A, 5000K, so I believe I do have KR4 driver.
But I cannot configure AUX leds, going into advanced mode does nothing. Not sure if that’s correct then. Any help please ?

Just to retrace the steps from the start (Anduril 2):

  1. do a factory reset first (hold down button while tightening the tailcap until the “exploding” animatino)
  2. switch to Advanced UI: from OFF, do 10H (10 clicks but the 10th click is a “hold”)
  3. configure Aux-LED:
    from OFF: do 7 clicks to change the Aux-LED mode (Low -> High -> Blinking -> Off)
    or from OFF: do 7H (7 clicks but the 7th click is a “hold”: continue holding will cycle each color / disco / rainbow / voltage)

I have come up with a much simpler way of doing a Mac install on Big Sur that does not need Xcode installed and is much simpler.

These are very minimal and simple instructions.

Open up a terminal window and type the following:

Confirm the installation of the Xcode tools

Let the home-brew system install - this may ask for your password

This will install the avrdude utility

This should have installed everything you need to flash your flashlights. To test that avrdude is installed and running type the following on the terminal window:

avrdude should return a version number.

From here you can install the new version of Anduril on your light following the Windows instructions from the step titled “Testing Communication To The D4V2”

For me this was a as simple as downloading the latest file and running this command line:

I hope someone finds this useful.
