Kusba 2.4 instalation process

[rastosk]

Hi i have received my kusba 2.4 from trianglelabs and i have to say what a beautiful work of art is this! When I was commissioning the accelerometer and following the guide:

6. Build the firmware

make

7. Find the storage location of the KUSBA. This will usually be sda1. Use this command one time with the KUSBA unplugged and one time with KUSBA plugged in (while holding down the button on the KUSBA) to verify.

ls /dev/

8. Flash the firmware.

sudo mount /dev/sda1 /mnt
sudo cp out/klipper.uf2 /mnt
sudo umount /mnt

Step 7 didn't make any sense to me so what i have done just skipped that step. Does this mean that my adxl will not work properly? adxl is connected to my pi when i do querry i get error on 2nd time is all ok no error that is normal according to instructiuons. The dilemma is will this work fine or i have do do step 7 some how.
Thank you for your help!

From the.looks, it's talking about the ls /dev/ command, so you can verify the device ID is in fact sda1.

When i issue ls /dev I get two devices one klipper and one adxl both are same looking as bellow

serial: /dev/serial/by-id/usb-Klipper_rp2040

[Will-wastelander]

That would mean the device has already been flashed, and you will need to hold the button while plugging in the USB cable to get to the bootloader.

So when I hold button down it will boot differently? When I type Ls/dev what should come out?

[xbst]

Just follow these instructions:

https://github.com/xbst/KUSBA/blob/main/Docs/v2-Rampon-Firmware.md#1-flash-rampon-anchor-to-the-mcu

You can flash the firmware on a Windows PC, it's easier.

[rastosk]

I remember doing that with adxl345 board. But looks like this kusba come flashed ! Do they come flashed from factory? If so that must be very old firmware on it surprised that this actually works. Gonna have to plug to PC and paste the new firmware

[xbst]

There's no one "factory" for KUSBAs. I open sourced the files so there are many vendors, and each vendor orders from their preferred supplier. Some even make them themselves. Either way, they don't come with the firmware, it needs to be flashed. I flash all of mine before selling them. I know some other vendors do that too, but not all.
Rampon, unlike Klipper, doesn't need to be updated often. So if you bought from me or another vendor that pre-flashes rampon, it should be good to go. No update needed until there's a new rampon version.

I actually had a problem getting mine to work, I have the 2.4 version

So I can only get this to work if I copy the firmware over every time I plug it in. So I need to hold the button down while plugging it in, then do these commands:

pi@klipper:~/klipper $ sudo mount /dev/sda1 /mnt
pi@klipper:~/klipper $ sudo cp out/klipper.uf2 /mnt
pi@klipper:~/klipper $ sudo umount /mnt

And the ls /dev/serial/by-id/ shows the device, but if then unplug the device and then plug it in again, the device does not appear.

Am I doing it wrong, or is the device defective.

This is the same issue for the Rampon as well

I bought the device from Unique Prints Shop in australia.

Hi pellcorp just follow this video and you will be golden. Supper easy and I don't use any command's only comment out # adxl when I'm done using

[pellcorp]

So it actually seems like have this exact issue #11

@rastosk I followed these steps to the letter, the issue is just like for issue #11, after I disconnect the device from the computer the flashed firmware gets reset. Just like issue #11 I can use the device just fine immediately after flashing, but it does not survive the device being removed from computer. So it seems like I have a faulty board (where the flash is reset / erased), I am chasing up a replacement from my vendor, fingers crossed they do the right thing.

[rastosk]

That sucks man I gotine from aliexpress trianglelabs

[pellcorp]

Seems like it just a random issue, and Unique Prints Shop will be sending a replacement tomorrow and they will test that the one they send me saves the flash image correctly. In the mean time I can use the faulty one, I just have do the mount cp, umount steps first.

[sreknob]

I just received one from Triangle Labs that has the exact same issue, will work after flashing but won't show up as a serial device after a power cycle. I presume there is probably an issue with pulling the chip into run mode.
