My next question was going to be "what *should* the EEPROM ID be... or what form should it take"? This (non-functioning) BBBW was purchased in Dec 2018 (just now putting it into service). I have another BBBW purchased in Feb 2017 that worked out-of-box (almost... it had a different issue with the "out-of-box configuration" that you also helped me with) and it shows:
eeprom:[A335BNLTBWA51650BBWG0378] model:[TI_AM335x_BeagleBone_Black_Wireless] So does a "correct" BBB Wireless EEPROM ID follow the A335BNLT BWA51*** BBWG0***] format, with the first wildcard digits some form of version of the wireless chip and the second wildcard digits the board or SoC rev? (spaces mine to separate the different fields) Finally, was my expectation/understanding incorrect that using /boot/uEnv.txt to override the EEPROM setting and force loading the wireless dtb would also work, without changing the EEPROM? (My thinking was to try that first, then if it worked it would validate the idea the the EEPROM was bad and *then* reflash the EEPROM). Thanks for your help, Robert.
