Thanks for the response. Any pointers on the quirk is greatly appreciated. All I am looking for is to get the NVME SSD working. IOPS is of no concern at the moment as long as it is better than SD.

Hi,
Booting the latest 32 bit Raspbian fails. Intel SSD 660. Orico Enclosure.

Thanks for all the help. I really appreciate it.You guys are awesome!!

Nope. I don't see any characters on that terminal. Only the initial message when I run the code.

I only see Loopback Test on /dev/serial0 at 115200 baud. Nothing else.

Thanks. Trying it out now.

Thank you very much for your response and directions. I really appreciate the help.
I verified the correct updates as u suggested by doing uname -a.

With the loopback test (TX to RX on PI with dupont cable) I just keep seeing b ' '

now i suspect hardware issues. may be tx or rx pin is fried ?

Thanks. I read that. From a config perspective I still don't understand what settings/parameters/overlays are needed on RP1 to enable a serial console? I was under the impression that a given version of Raspbian would take care of that.

PI2 the serial console works!
PI1 Still does not.
All help appreciated

Hi,
On a PI 4 The serial console seems to be working. With the same exact setup including the same SD card, Cable, etc If I switch to a PI1 the serial console there is no output. Can someone help me please.I am on the latest 32 bit raspbian.
Thanks
