Thank you for testing! Without the UART serial connection, it's hard to say where / why the lockup is happening. AFAIK, you shouldn't have issues the number of reflashing attempts. Just make sure you never power down the unit while flashing. :) I'll be back at home with my D unit in a couple of...

I had suggested that we have a dedicated "dev" forum for anyone involved with building/testing firmware updates, and maybe even a dedicated one for the excellent hardware mods? It's awfully heard to track all the various aspects of this unit.

Ok, I've created a new version of Rev D firmware---thanks for the feedback, @Hook Line and Tinker ! I wish I could test these builds first, but as I mentioned earlier, I'm traveling for a week and not gonna fly with the unit---especially on float planes. :) I've made this more of a diagnostic...

Thanks for the report! I did leave an inclusion to try to use the exposure section of @0dan0 's hist.c code, and that may have locked up the unit.

I have with an update on the Type D firmware work: @0dan0 's overlay code reads a custom 7x12 bitmap font from a specific firmware address to render all the on-screen text (FPS, Qp, ISO, exposure, WB gains, etc). I hadn't come across any notes on the font embedding, so it took some binary...

Looks like more and more model D's out there! I've been preoccupied the last couple of months with other work, but I'm getting back on track with moving firmware D updates in the coming weeks.

I'd like to be working on this effort---I brought up before, but it sounds like it's not a good idea to have a temporary "fix" that just hard codes the Qp value as it will crash the encoder according to @0dan0. In his notes that he posted a while back (a TXT file with some of his changes...

This approach involves drilling new holes into the chassis that the lens board mounts to. I think getting the 12mm macro lens is the better way to go, and keeps the alignment in place. You do have a Type D unit, as that sensor board is stamped 2025.

The plastic posts are held by screws that are easily removed once you have separated the case. So the two ribbons you see in that picture---the narrow one goes to the button control panel on top of the unit. Before you pull apart the halves further, move that top panel to the other half so that...

Thanks for posting this! I didn't realize my heat gun was set as hot as it was---I partially melted one side of the mount while I was trying to remove the glue bead. I'll be back on track with my lens upgrade in two days when the new mount from that kit you linked to on Amazon arrives!

@0dan0, in Type A/B/C mods, were you able to identify an address that stored the current buffer address that was being drawn to? I saw that ipl getimepath reports the current buffer frame.

@0dan0, can you share your last version of the hist.c for that display? did you have that blinking issue I had?

Ok, thanks for that input, @0dan0. I've started to use the BSim plugin with Ghidra and the AE function I was working with before in stock D does seem to have a lot in common with the A/B/C AE function. I'm hopeful with at least that, but I haven't identified the expo_iso address yet.

Thanks for the quick input, @0dan0. Are there other people who were active in past mod efforts?

@0dan0 and the rest of the community, is it worth putting together of list of what's desirable to change in the stock firmware D and what's less needed now? From what I can, the only mod you've made that's not as necessary is the 1600x1200 adjustment, but the rest seem worth porting. I'd like...

I believe @0dan0 posted a revision of @Deano 's dover to fit his lens mods better. @Deano has a different lens spacer in place if I remember correctly.

@0dan0, I can confirm that the ERR:UIFlowWndMovie_OnTimer() Record400MinTimeOut 0 is "normal" for stock D. I would often get continuous motor on some firmware changes I tried to make, but not with stock D firmware. This is strange---sounds like a self-check/diagnosis is failing. Do any settings...

@0dan0 , maybe I missed it in your notes but how did you update Qp in previous mods?

Understood. I would like any insights you might have @0dan0 on adjustments to Qp---is that easy enough to swap out as a constant?

@0dan0 I'm not sure where you're at with diagnosing the hardware issues you've having, but I'm happy to look into the crash if you want to share the current RBN and C++ files you're in dev with. As I mentioned in an earlier post, specifically with the histogram, I had a lot of crashes that...
