I may have unintentionally committed it wrongly?
<whitequark[cis]>
do you have one of those MEC16xx devices? that would be cool, cause I no longer have one

I do, i bought a dead laptop, that I repaired (it had shorted capacitor on the main power rail, and a blown fuse), but after the repair I was greeted with a supervisor password. Online sources say that reading, erasing, and writing the chip gets rid of the supervisor password, cause it's supposed to be in a secure are that gets zeroed this way.

<purdeaandrei[m]>
it takes about 12 minutes to read 192 kilobytes, is that expected?
<purdeaandrei[m]>
Read seems to have been successful , I read it out twice, and both times got the same binary
<purdeaandrei[m]>
I then did an emergency-erase. That started up the fan at full speed.
<purdeaandrei[m]>
Write is still going on, I think it's been running for 30 minutes now, still not done
<whitequark[cis]>
purdeaandrei[m]: you might want to raise the JTAG frequency
<whitequark[cis]>
try -f 2000
<whitequark[cis]>
or -f 4000
<whitequark[cis]>
purdeaandrei[m]: as expected
<purdeaandrei[m]>
looks like emergency erase may be causing further commands to not work.
<purdeaandrei[m]>
I just killed the write, and reran it in verbose mode
<purdeaandrei[m]>
and it just sits waiting after D: g.applet.program.mec16xx: MEC16xx: halting CPU
<purdeaandrei[m]>
so that shows the original mec code never correctly halted the CPU
<whitequark[cis]>
ouch
<purdeaandrei[m]>
Also looks like the issue with writing is something simple. when I did the write, the erase succeeds, however the programming operation doesn't. But when I commented out the erase, the programming operation succeeds, I think it looks like we're just not waiting enough for the erase to get it back into an idle state.
<whitequark[cis]>
quite possibly
<purdeaandrei[m]>
Well, crap 😦 I wrote back the same data I read out (verified by reading again), and now the laptop's not starting up anymore 😦
<whitequark[cis]>
interesting
<whitequark[cis]>
fortunately you have the perfect tool to find out why :D
<purdeaandrei[m]>
yeah, lol, just didn't think i'd end up debugging arc code 🙂
<whitequark[cis]>
i wonder if it's arc code
<whitequark[cis]>
so, it has a EEPROM
<whitequark[cis]>
have you read or erased that?
<purdeaandrei[m]>
I didn't touch it
<whitequark[cis]>
i assume not, it seems independent from main memory
<grazianom[m]>
Thank you. Isn't the product (hw design) done, though? Is it still the acquisition of parts that's holding it back?
<grazianom[m]>
And do you happen to know how early 'early bird' was? I backed in December 2020.
<grazianom[m]>
I see I am not early bird from the update
<grazianom[m]>
* ~~And do you happen to know how early 'early bird' was?~~ I backed in December 2020.
<modchatbot[m]>
I am in the same boat as you (backed in Feb 2021). I think the design is finished or at least stable. It's the manufacturing part that's pending now. Someone just assembled their own Glasgows at home, so the components (or their substitutes) are likely available on the market: https://discord.com/channels/613131135903596547/613461005392936961/1193118660345221180
<grazianom[m]>
OK cool. Here's to hoping it actually ships soon.

That is odd. You have to change your shipping address with CrowdSupply though. This is from the cS documentation:
<esden[m]>
> You can change your shipping address by going to your Crowd Supply account page, choosing the open order you want to change, and then clicking the "Update Shipping Address" button. We are unable to update billing addresses. If you must use a different billing address, please cancel and replace your order.

Holy shit, I had no idea 1BitSquared is not profitable... Man, it is time to increase the prices... I think that would be better for both 1BitSquared and all of us... 😄 You can focus on products and we can have better experience...
<esden[m]>
nemanjan00 (@_discord_268952761595461632:catircservices.org) There is a limit to that. I did increase them somewhat to account for the increased part prices and inflation overall. The issue is among others that I am not bringing new products on the market due to the overall backlog. The post campaign sales is what usually balances things out. But in this case I can't launch icebreaker-bitsy campaign until I get control over the Glasgow
<esden[m]>
campaign, and I will not finish the Glasgow campaign if I go bankrupt, so I need to do consulting. (yeah it is a bit of a vicious cycle but we will get through it! 🙂 ) At the end it is all hinging on me not having enough hours in a day.
<esden[m]>
I am at least slowly getting the situation with existing products under control and keeping them stocked. That was an issue for the longest time in itself.
<nemanjan00[m]>
Your products are usually replacement for commercial products of 10x or 20x price of your products... And due to being opensource + quality accountability that comes with that, they are usually better in a lot of ways... I would be more than happy to pay a lot more for glasgow than what you charged...
<esden[m]>
A lot of people have a certain price expectations. ("I can build it myself for less!" attitude) I try to charge what I think is fair and what I would be able/willing to pay. But you might be right that I am not charging enough. Things to consider in the future.
<modchatbot[m]>
I wonder for some tim if "$364,196 raised of $25,000 goal", "1,456% Funded!" in the campaign made things easier or harder for you. Would it be more economically manageable with 25k of orders or 14x more?
<esden[m]>
Not sure how much it would have helped with Glasgow to have the foresight. If I had foresight I would postpone the campaign until the chip shortage subsided. 😄

You'd have brought a ton of chips to resell them at a premium :-)
<nemanjan00[m]>
Imagine if price was just 20$ higher...
<esden[m]>
@galibert Great idea! 😄
<galibert[m]>
but your crystal ball was in the shop, too bad
<esden[m]>
I appreciate the concern and the thoughts. 🙂 The main thing I need to do is consistently put in few hours here and there to move things forward. And that is what I am doing.
<nemanjan00[m]>
Even those who claim they can make it for less, probably will not... Let's be honest, nobody could have predicted the shortage, but, their solution was big margins, so they can compensate for unexpected...
<galibert[m]>
And in any case raising the prices now wouldn't clear the backlog
<esden[m]>
Yeah, I now have to finish eating the soup I cooked... that is the challenge that I am working on. 😄

I found the bios update utility and extracted the MEC image from it and it 100% matches what I have dumped from the MEC (the file has an extra 32 bytes header but the actual image is all the same)
<purdeaandrei[m]>
really not sure what could be wrong maybe I did something stupid, for example shorting something out as the glasgow was dangling around the laptop motherboard 🤷♂️
