Have you tried typing boot to grub

Mmelta101 Have you tried typing boot to grub

what you mean? On serial there is no edit option on grub entries. Either boot or boot to recovery
Both failing if hash of M2 is diffrent than original

melta101OP•12/3/24, 7:01 PM

I mean grub shell

AlexTryHarder•12/3/24, 7:01 PM

Oh, there is no grub shell, just predefined boot options

AlexTryHarder•12/3/24, 7:02 PM

something like that, without last option tho

If that will work I will be suprised

melta101OP•12/3/24, 7:04 PM

AlexTryHarder•12/3/24, 7:04 PM

Thanks, will let you know, could waste whole day on it!

melta101OP•12/3/24, 7:04 PM

May you resolder it back in 1 piece

Wwafa_ath Hi @Techist

Abstract? I'm a bit lost.
Please what's required of me in regards of my project presentation next week Wednesday?

Wwafa_ath That called tag collision in RFID, it's hardware limitation

fei•12/4/24, 3:44 AM

I see, if thats teh case im talking to the manufacturer agn

fei•12/4/24, 3:44 AM

it seems they do offer other alternatives with anti collision. I guess ill try that

fei•12/4/24, 7:18 AM

Yea, have been just playing with the reader settings for both EPC, TID and User data

fei•12/4/24, 7:18 AM

EPC just have better read ability compared to TID and User data, it seems or im just doing it wrong

fei•12/4/24, 7:19 AM

wafa_ath•12/4/24, 7:24 AM

Have you tried lowering the power slightly or tweaking the inventory delay to see if it helps with TID and User data? , (my brother used to work with it and install them ,i am taking advices from him )

fei•12/4/24, 7:26 AM

I have but I can definitely check again, also does the rfid tag matter as much or is it just the reader?

wafa_ath•12/4/24, 7:28 AM

The reader’s capabilities are key

fei•12/4/24, 7:32 AM

If thats the case hopefully the new reader im ordering works well enough for my use case, but ill definitely check with the power and inventory delay settings again to make sure if its any better for TID, as i needed a constant ID and all the logic works in software instead of inside EPC or User data

fei•12/4/24, 7:32 AM

If not, ill have to fly to China to get the required equipments

That's a beautiful PCB,
Did you create those 3D Packages?

Thank you, I usually check grabcad.com for 3d packages if it's not available on Kicad

melta101OP•12/4/24, 8:54 AM

nicee
it's quite rare to get such detailed 3d files

Afuevu•12/4/24, 8:56 AM

Yeah, I was amazed when i checked grabcad

Mmelta101 Press C

AlexTryHarder•12/4/24, 9:18 AM

Sadly pressing "c" wasn't a case

melta101OP•12/4/24, 9:18 AM

what does it boot in when click on those volumes?

AlexTryHarder•12/4/24, 9:19 AM

As M2 board was overwriten with linux image, in first attempt to boot from it,

AlexTryHarder•12/4/24, 9:21 AM

Indeed says on top lol, tought it's a grub

melta101OP•12/4/24, 9:21 AM

there should be some key binding to it

melta101OP•12/4/24, 9:21 AM

to access shell

melta101OP•12/4/24, 9:23 AM

what about esc key

AlexTryHarder•12/4/24, 9:30 AM

After failed boot from any of options, it's dropping to the shell

it's chill
no one knows everything
was it able to work?

AlexTryHarder•12/4/24, 9:58 AM

Will attempt now, but looks very promising, especially with savenv command that will write it back to flash

segfaultdev.elf•12/4/24, 9:59 AM

@melta101 have you worked with SPI ILI9XXX display?

segfaultdev.elf•12/4/24, 10:00 AM

I thing we can achieve 60fps with a good stm32
