Hi, I'm a Lennar homeowner and my pre-installed Ruckus ICX7150-C12P is stuck in boot mode after a power outage corrupted the flash image. Hoping for some help.
Boot output (same every time):
- Bootloader loads fine: Ruckus Wireless Bootloader 10.1.15T225 (Jan 30 2019)
- Hardware: ICX7150-12 (POE), PVT1, SYS CPLD VER 0x4, Released Ver 0xa
- Primary fails: "NAND read from offset 0 failed -22" → "Bad FIT kernel image format!" → "ERROR: can't get kernel image!"
- Falls back to Secondary, fails the same way: "NAND read from offset 4000000 failed -22"
- ECC read errors on both partitions before each failure (iproc_nand_read_page returned 2, multiple ecc_errors)
- Then drops to ICX7150-Boot>
My setup:
- Mac connected to the USB-C console port
- Silicon Labs CP210x driver installed, device is /dev/tty.SLAB_USBtoUART
- 9600 baud (tried both screen and picocom)
The problem I'm stuck on:
I can reach ICX7150-Boot>, but it won't stay stable. Right after the prompt appears, the console starts receiving fragments of the switch's own boot banner ("23:08OK", "ICX7150-12 (POE), PVT1", "SYS CPLD VER: 0x4"), which get read as commands ("Unknown command..."), and it snowballs into a continuous self-repeating loop that makes the prompt unusable. This happens identically with local echo turned off and across different terminal programs, so it doesn't seem to be a terminal echo issue on my end. The "Enter 'b' to stop at boot monitor" countdown shows 0, so there's basically no window to interrupt autoboot.
What I've already tried:
- Multiple USB ports/cables, reseating, hubs
- screen and picocom with echo and flow control disabled
- Pre-streaming 'b' before power-on to try to catch the zero-delay boot window
Questions:
1. How do I get and hold a stable ICX7150-Boot> prompt given the near-zero bootdelay and this self-echo loop on the USB-C console?
2. I have the recovery boot code (mnz10115.bin), recovery image (SPS08090k.bin), and final image (SPS08095sufi.bin) ready for a TFTP recovery — can someone confirm the correct procedure for this unit?
3. Given the ECC errors on both partitions, is this recoverable via software, or does it point to a NAND hardware failure needing an RMA?
Confirming this is a Ruckus setup in a Lennar home. Thanks in advance for any help.
