### Basic Information: Printer Model: ender 3 v2 MCU / Printerboard: 4.2.2 GD32F303 Hey, I tried flashing Klipper on my Ender 3 V2 (board 4.2.2 GD32F303) following the config guide, but no luck. - Screen is stuck on the Creality logo - Tried disabling SWD at startup — still not working - Printer doesn’t show up in the web interface - 1gb samsung sdcard formated to fat32 with 4096 ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/c/0/c067e66b5f62939f55ed1a7e145c23a659b00e31.jpeg) steps i do: Started my Raspberry Pi Zero 2 W 1. SSH into the Pi 2. Ran `make menuconfig` with these settings: 3. Ran `make` 4. Took a 1GB Samsung SD card, formatted it to FAT32 with 4096 allocation 5. Copied the generated `klipper.bin` to my PC via FTP 6. Renamed the file to `Ender0508.bin` (to match the current date) 7. Transferred the `.bin` file to the SD card 8. Inserted the SD card into the printer 9. Turned on the printer (display was connected — not sure if that matters?) 10. Screen is stuck on Creality logo 11. Waited ~1 minute 12. Connected Pi to printer using USB-A to Micro-USB 13. Ran: `ls /dev/serial/by-id/*` — **nothing shows up** ---

Make sure there is only 1 file on the card Rename the file. The 4.2.2 card requires the .bin file have a name DIFFERENT than the name of the file that was used to flash the last time. I prefer to keep my names short (8 characters) but not a requirement. An example e080425a. E for ender then the 6 digit date and then a for first try of the day. Putting in the date prevents me from EVER recycling a name. ---

What’s a “1gm” SD Card? Use as low a capacity SD Card as you can find. I normally use a 4GB card around for this purpose and I still have a 2GB card or two around as well. ---

Can you go through the process that you’re using to update the firmware? Please be as precise as possible and list all file names and show what’s on the SD Card. You should be following the process: ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/d/2/d20f76777b17b11761f829c43c0c60705de29dc3.png) ---

One thing jumped out at me: ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/0/9/09ba082fe9eb6576c799068a8e7a0dd0d97ab9f6.png) Could you try not renaming `klipper.bin` and loading the file as is on the SD Card? I seem to recall that the file name has to be eight characters - your name has nine. If that doesn’t work, I’m wondering about: ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/8/9/899ec0bc048ac32843b3b12538ebbcd742927a8c.png) How do you know the `klipper.bin` file was transferred correctly without any inadvertent changes? What is the process you’re using for transferring the file and it’s contents? ---

Try transferring it back under a different name and then doing a kdiff on the two files: [https://kdiff3.sourceforge.net/](https://kdiff3.sourceforge.net/) That will tell you if there are any problems with the file transfer. Personally, I use NotePad++ with its NppFTP plugin. ---

i think its the same file its copied using ftp should i load config file before i make framework or its independent ? ---

> [@michisha](#): > > i think its the same file its copied using ftp What makes you think that? Make sure the two files are exactly the same length (and the same length as the file that is on your PC). What you’re describing is that the Ender 3 main board is not recognizing that there is a file with new firmware. Causes for that are: 1. The file is not in the correct format. Now, I should have asked how did you identify your board and, looking at the OP you have identified it as a GD32F303, how did you do that? 2. The SD Card doesn’t work (which seems unlikely because you can read it on your PC) 3. The SD Card slot on the main board doesn’t work. I’ve discounted this because I assumed that you did 3D prints with the firmware out of the box before trying to install Klipper - was this a valid assumption? Thoughts? ---

1. open the cover of the mother board and look on it 3. after failed instalation i downloaded marlin frameware for my ender 3 v2 and it allso has a bin file and its flashing the frameware ---

How do you know it’s flashing the firmware? Are you using a different version from before with any features/indications that show you that you’re putting in different firmware? ---

Sorry, I misunderstood the question earlier. I’ve confirmed that the SD card and the printer are working fine — I successfully flashed a different custom marlin firmware (not Klipper) using the same setup, and it worked. So it seems like the problem is with the **Klipper `.bin` file** I built — the screen just freezes on the Creality logo and the Pi can’t detect the printer over USB. Any idea what might be wrong in the build process or config? Thanks in advance! ---

What happens when you load the Creality firmware - you get the logo on the user interface and then it changes into the firmware? Where did you get the `make menuconfig` settings? Have you tried any others? You’re using the rPi Zero 2W as your host. How are you connecting it? ---

Yes when i load firmware i get the logo and the screen. I got the make menuconfig from the config file of ender 3v2 and ender3v2 pro tried all of them i am connecting the pi like that microusb to usb\> usb to micro usb\> micro usb to ender ---

Usually you will find an answer among [Issues flashing the printer board](https://klipper.discourse.group/t/issues-flashing-the-printer-board/14015) Note that we had users here that: - Tried up to 5 different SD cards - Multiple USB cables before finding one that worked. > [@michisha](#): > > Interface: `USB (on PA11/PA12)` This is definitely wrong.
