Hello,
I have an Ettus B210 device that I have been experimenting with for
some time. I had a need to turn on and off the device on a remote
host. I intended to apply the bootloader for fx3 to the device. While
playing around with the b2xx_fx3_utils, I loaded the bootloader of the
device with “usrp_b210_fpga.rpt” by mistake. After following the steps
by Benito Horta discussed in the B200 shows up as Cypress FX3 USB
Bootloader Device FIXED steps taken
<https://usrp-users.ettus.narkive.com/7S6MYwCo/b200-shows-up-as-cypress-fx3-usb-bootloader-device-fixed-steps-taken>,
I managed to recover from this situation somewhat.
Problem:
*
Device cannot be initialized though api calls (such as from
Python) or uhd_usrp_probe etc.
Error Message:
*
"Error: RuntimeError: B200 unknown product code: 0x3120"
Cause:
*
My suspicion is that the device mb eeprom: serial, name and
product ID are corrupted (from what I understand from the error
message and the uhd_find_devices output).
Note that the uhd_find_devices output is,
[INFO] [UHD] linux; GNU C++ version 11.3.0; Boost_107400; DPDK_21.11;
UHD_4.3.0.0-release
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
serial: SP48A1s:
name: 6 25%
product: B2??
type: b200
I am using UHD-4.3 and Ubuntu 22.04. I tried loading firmware, FGPA
and bootloader files using ./b2xx_fx3_utils.
I read About the Motherboard and Daughtercard EEPROM on USRP Devices
<https://kb.ettus.com/About_the_Motherboard_and_Daughtercard_EEPROM_on_USRP_Devices>
and I need guidance on using the ./usrp_burn_mb_eeprom tool. Has
anyone had anything like happened before? I worry the eeprom writes
are undoable, nevertheless, any suggestion about the issue is appreciated.
Cheers,
Eden.

What happens if you use "--read-all" on usrp_burn_mb_eeprom?
That will give you a list of what it thinks the various keys in EEPROM are.
