Soo..... This code should now be into the territory of testable.
I've tested on 3x TS100's so far.

To test still:

  • TS80
  • TS80P
  • MHP30

If anyone out there wants to give it a shot to just test the runtime version would be fantastic.
Just grab the runtime.hex from the latest action

If you can run runtime and make a bootloader backup would be fantastic, and if you could note the md5sum of your backup + your bootloader version would be awesome.

@Ralim

😭Apparently, I bricked my beautiful TS80P!

I did follow all the instructions you provided, starting with flashing runtime, backing up the original bootloader and finally flashing your bootloader.
The result showed up as you predicted:

... but after unpluging and repluging the USB cable the screen stayed black! 😔🤷‍♂️

Is there any chance of reviving the TS80P?
Which st-link would I need?

Is this one sufficient?

Please don't get me wrong, I know that this is my fault, since you only asked to test runtime.
But honestly: I was that much excited, that I did not read the text carefully the first time, because I wanted to get this immediately onto my iron. 😩🤦‍♂️

thanks in advance

I did just say runtime mode :/ mostly as I've not finished testing it across all my devices.

Have you checked that if you hold the front button and plug it in that it doesn't appear in device manager / lsusb ? If it does show up but the screen stays black then you can probably just reflash runtime and then flash it with the screen starting off vasc it's most likely the thing that's dodgy is the OLED code.

But yes that st-link or the many like it will work, is it doesn't show up on USB. Not sure what the easiest way for you to buy locally is but those units work great as little clones. Often they are $3-4 USD ish around here fwiw.

@Ralim
Good morning Sir,
thank you for replying in time. 😃

I already tried to reflash runtime, but unfortunately no luck what so ever.
So next step is to buy the st-link?
Do I need any adapter apart from this?

Ralim commented Feb 1, 2022

Yeah okay if that's not working, an st-link, and you also want a USB breakout so that you can access the USB pins .

I use a USB-A socket breakout that gives me the VCC,D+,D- and GND pins.

I then supply 5v,GND from the st-link. And wire up D+ and D- to the SWD pins and then you can reprogram it without opening.

Alternatively one could cut up a USB cable, but if you can buy a cheap breakout that is easiest

Yes that worked! The hardest part was to get the STM32 ST-LINK Utility software, though! 😓

No reason for you to feel bad however! 😃

This was clearly my fault and obviously the consequence of my impatience! 😁

So I am here for more testing!
What's next?

Ralim commented Feb 5, 2022

You have found something interesting..

Could I ask you to repeat what you did last time with the latest action builds; and also record the commands you run?
I've done testing on my TS80 and TS80P now and they also work fine 😓
If you can reproduce the issue, could you save our your flash as a hex for the case where it doesnt boot ?

@Ralim

Thank you, this time it worked immediately! 😃👍

I like the instant powerup very much! A lot better than the stock bootloader. ❤

2 things I would like to issue though are:

  1. Orientation being in lefty mode (Maybe you could provide 2 separate builds left and right.)
  2. Logo not centered

@Ralim

Ralim commented Feb 5, 2022

I dont know if its worth doing lefty/righty modes 😁 Its just more firmwares to confuse people :P

Should probably centre the logo though

@Ralim
Would you mind telling me what I need to change,

  1. to get righty mode? (Are there not more righties than lefties out there?) 😁
  2. to set the brightness to the lowest possible value?

0x80, 0x0F, /*16 == max brightness,39==dimmest*/

or / and

0x80, 0x81, /*Brightness*/

I would like to adapt my fork only.

Ralim commented Feb 8, 2022

I dont want to go minimum brightness, but rather middle of the range :)

I'll update to make it flipped for the TS80's so its the right way around for righties.

Good morning Sir.

I dont want to go minimum brightness, but rather middle of the range :)

Yeah I got that, but as mentioned above, I wanted to only apply this to my fork.

I will not start a PR to the mainline. 😊

Unless you do not want me to build my own.

I'll update to make it flipped for the TS80's so its the right way around for righties.

That would be great!

This is the bootloader

Can you provide output of lsusb ?

Noting your dfu-util is older but it should work fine for this.

You may need to run dfu-util with sudo depending on permissions on your usb devices

BTW - I was able to flash runtime.hex only in windows 10 x64. dropping the same file in ubuntu alsways giving runtime.ERR.

For in ubuntu you copy the hex twice to get it to flash (first will .err, second works)

So its showing up on usb, so it may be either sudo access or out of date dfu-util i'm afraid

I have backed up TS80 DFU 3.45, no one else uploaded his fw hash yet, is there any way to be sure it is ok? I don't fully understand the bytes thing. Maybe @Ralim would you mind checking if I send the file directly to you? My sum is fadae45b4249d4f156c30b7d4b0a853e.

The runtime works perfectly.

I may have something odd going on with my TS100, when it's in DFU mode it says it's 3.45 but the md5sum of the backup matches the one listed for 3.42.

Fun bit of trivia I noticed while checking this out:

$ strings backup.bin | grep -Ee '3.{3}'

upgrading my Miniware TS80P with DFU 3.50 to IronOS-DFU 0.2 worked like a charm. I have used macOS 11.6 and usb-c -> usb-c 2.0 cable connected to one of the ports on my Mac.

I did boot new boot loader at runtime, made a backup, checksum did confirm 3.50 dfu version and then flash boot loader in place of existing one. all I had to do after is flash firmware itself using dfu mode.

hi, trying runtime version on mhp30 and it gets renamed to RUNTIME.NOT instead of err or rdy extension.
main IronOS firmware could be flashed just fine.

all i do is copy runtime.hex to device.

is there anything else i could try?

Anyone have thoughts on why I'd get a black screen after flashing runtime.hex? dfu-util also doesn't see any usb device when booting the runtime.hex after flash.

... but after unpluging and repluging the USB cable the screen stayed black! 😔🤷‍♂️

Is there any chance of reviving the TS80P? Which st-link would I need?

Is this one sufficient?

Please don't get me wrong, I know that this is my fault, since you only asked to test runtime. But honestly: I was that much excited, that I did not read the text carefully the first time, because I wanted to get this immediately onto my iron. 😩🤦‍♂️

thanks in advance

Same here!!!!😭

@L1cardo
But this is not final if you have a device with a ST chip.
If so, you need a STM32 ST-LINK V2.

This solved my problem.
I hope that helps.

i tried and Sequre S60 and it works well with IronOS-dfu

runtime worked like charm but flashing bootloader triggered some protection in my case (turns out read out protection bit was set) and triggered erase.

restoration was all about opening, connecting STLINK/SWD (there is pads with D=SWDIO, V=3.3V, G=GND, C=SWCLK under display) and shorting 44th (boot0) and 43rd (gnd available there, somehow actual ground didn't work here) pin permits for iron to be detected by STLINK.

for whoever needs help locating pins - they are 5th and 6th pin counted from bottom up on the left side of iron when you hold iron tip holder toward yourself and usb port outward. when you hold iron like this - chip gonna have round/dot indent indicating first pin in left bottom corner.

read out protection could be removed either by older ST-LINK utility or by OpenOCD.

anyway, IronOS-DFU works well on Sequre S60 :)

i have got second ts80p since i did like original one... and looks like they changed some things.

i have DFU bootloader 3.50 (1.30 firmware) with 1805EC83F64C74DD89F87A1B57B7E631 MD5 and it can not flash any IronOS firmware by drag and drop. i tried IronOS-dfu and it is the same.

i did connect it through SWD and got a bootloader and 'full dump' from there.
if did try flashing IronOS-DFU 0.20 and DFU 'starts' with a black screen now and if i connect it to any computer - i get 'bad usb descriptor'. i am able to rever it back to original 3.50 bootloader (it becomes quirky with new DFU and it took me few attempts to make it recognized by ST-Link)

i tried different usb ports, different connections (usbA / usbC), different cables (thunderbolt3, thunderbolt4, usb2 usbC/usbA, usb3 usb-C/usbA) and still get bad file descriptor.

any suggestion what else i could try? do i need to provide dumps?

no wonder it retails for half of its original price now.

i was able to flash using st-link instead of cube programmer and it booted bootloader with working display. flashing correct ironos was straightforward.

something something hardware changes, something something compatibility gets worse (quirky?)

this ts80p with 3.50 dfu had v1.3 board revision.
