Kernel Panic on Raspberry Pi 4 Running Raspbian Bullseye with USB Boot Configuration
I need help solving I've encountered a strange issue with I'm trying to figure out I'm stuck trying to Can someone help me understand This might be a silly question, but I'm experiencing a kernel panic on my Raspberry Pi 4 when attempting to boot from a USB drive with Raspbian Bullseye. The setup was initially working well when booting from the SD card, but after setting the USB boot option and flashing the OS to the USB drive, I am greeted with the dreaded `Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)` behavior. To troubleshoot, I followed these steps: 1. Verified that I have the latest firmware by running `sudo rpi-update`. 2. Re-flashed the USB drive multiple times using both `Raspberry Pi Imager` and `Etcher`, ensuring that the drive is formatted correctly with the FAT32 boot partition. 3. Checked the configuration in `/boot/config.txt` and ensured I'm using the right parameters: ``` program_usb_boot_mode=1 ``` 4. Tried different USB drives, including a Samsung and a Kingston, both of which are known to work. Despite these efforts, the kernel panic continues. When I try to connect via UART to view the boot logs, I see the following output just before the panic occurs: ``` [ 0.000000] Booting Linux... [ 0.000000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) ``` I've also tried editing the `cmdline.txt` file to explicitly point to the root filesystem, but that hasn't yielded any different results. Is there something specific about the USB boot configuration that I might be missing, or could this be related to the USB drive compatibility with the Raspberry Pi 4? Any insights or experiences with similar issues would be greatly appreciated! Any ideas what could be causing this? This is happening in both development and production on macOS. Hoping someone can shed some light on this. I recently upgraded to Bash 3.10. Any examples would be super helpful. I'm coming from a different tech stack and learning Bash. Am I missing something obvious?
