Weird behaviour during and after flashing

Another question about flashing firmware.. I recently ordered some Oshpark boards and thought I would try my hand at building my own drivers from components purchased myself (at Digikey in this case). The driver in question is this one: https://budgetlightforum.com/t/-/39279 I have tried flashing a number of firmwares onto it, namely "bistro" by ToyKeeper. (Love the firmware BTW.) I guess my question is this: since this driver is a dual channel driver but uses 7135 chips on both channels, is that a problem for using firmware such as bistro which is a dual channel firmware but is designed for a 7135+FET layout? If it is an issue, how might the firmware be tweaked to make it work? Back to the issue at hand, I have flashed the hex file (confirmed to be working on a 7135+FET driver) which flashed successfully, but when connecting the driver to power, nothing happens. Also, when hooking up the MCU to the clip, the led lights up. I have never had that happen when flashing the 7135+FET drivers.

Here is a shot of the driver:

Perhaps someone can identify if any of the components are wrong.

Any help would be greatly appreciated.

The solder joints look good. Did you use solder paste and hot air?

This is the Attiny pinout from here: http://toykeeper.net/torches/x6v2/manker/bistro.c

If you have a multimeter, try probing the MCU pins while the driver is powered and see if everything is okay.

I seem to have soldered the diode on backwards…

To answer your question, ryansoh3, I did use paste and hot air. Were you just curious, or does it make some kind of a difference? I always use solder paste for pcb work.

Glad you fixed it.

I thought the solder job was done very well and was wondering how you did it. A soldering iron wouldn’t have turned out as nice.
