No WiFi after SD issue

[tniccum21]

Hey all, I'm working my way through getting my machine running again... It ran on my shelf without issue for a couple years...

A few days ago I looked up at my shelf and all my retros were purring away with blinky lights, but the Imsai was dark...

So tonight I pulled it down and as I suspected the SD card had died.

So... I downloaded the software, created a new SD card... Connecting a serial monitor, i see the stream below - not seeing any obvious errors.

The lights are on, when I turn it to PWR ON, but no IMSAI shows up on my wifi...

One question: is there a limit on SD size? I had a 64GB laying around and used it... but I know on some of these there are limits.

Thanks,

Tom

Additional note:

I tried to access/check/set the NVRAM configuration, but that's not working...

I power off, hold up examine, hit reset, release examine. Nothing. No lights whatsoever.

HOWEVER... I now see imsai (but not imsai8080) on my network....

If I reset from ere, I get the run light lit, and most of the lights are on and something appears to be running.

After rebooting (pressing "EN" on ESP) i'm now getting wifi messages (imsai showing up on newtorks, but not imsai8080 still):

OK I also updated the firmware to 1.13.0 in case the firmware was out of compatibility with the newest image, etc.
Boots OK, and now i figured out the right reset button to push,
the NVRAM setup works.

However after PWR ON, RUN, i see the imsai wifi, but not the imsai8080.

It seems that on bootup there is no imsai on wifi, but if II enter the NVRAM setup, and exit - then imsai shows up....

I upped the logging to "info" level and now detecting some issues - also in a boot loop, where it's trying to reboot after that Guru Meditation Error core dump.

===================

Boot log is showing 1.13.0 as the firmware version.
