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 "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 "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.
