I do not have a problem with JTAG, and I have a large collection of JTAG
and similar debug probes.
But I rarely use them.
My work is inconsistent. I move from BBB's to Opi's to Freescale K70's to
STM32's to PIC32's to PPC405's to RISC-V's to TI CC1310's .
It is difficult to become
Good job glad you were able to convince the client. I've been in situations
like this where they wouldn't change the hardware its a goldmine if your a
consultant. I'm also encouraged you were smart enough to use a jtag its folly
to do board bring up without it unless you want it to take longer

I have pretty much done what you suggested - I built a custom u-boot, using
patches from Mr. Nelson that assumes a BBB,
I also moved the Debug Uart to Uart 4.
Still no joy. Do not get to USR0 lighting up.
I fired up CCS 7.4 and my Segger JLink and the CCS instructions - I
Thank You.
My advice to all of my clients - including this one is that - Unless you
are GM and making a million of something, the hardware design should
deviate the least possible from whatever reference design or development
system you are using.
It is just not possible to save enough

i.e. if necescary sets the pin mux or whatever else might be needed ?
Basically some BBB GPIO bare metal

I followed these instructions
and additionally set
CONFIG_CONS_INDEX=4 in the defconfig.
Held the boot button and cycled the power.
The USR0 LED did not come up.
Can I presume there is a more significant issue than that the eeprom is
blank ?
Thanks;
I would love to get confrontational with the hardware designers, but I am

It is possible that UART0.TX and UART0.RX have been brought out to VIA's -
but they are not labeled, and I do not have a PDF or gerber of the board
layout.

I design hardware for a living.
You need to throw this back at the hardware designer and have him/her
present you with a workable board.
They took a SIP designed to take all the hard work out of making a
BeagleBoard clone and managed to mess things up enough so that it
won't boot and you can't
I have been searching arround all day and gathering more information.
The "Clone" board appears to be an Octavo SIP and is partly patterned after
an PocketBeagle.
There is also a display similar to that of the BB 4.3 Cape.
The SIP eeprom is unlikely programmed, there is no eeprom to tell
I did not do the hardware.
I did not have much input to the hardware or UART0 would have been brought
out
I will forward that question.
But I beleive the board is using the Octavio SIP.
Further that makes sense with what I am seeing.
Power up - power LED comes up, no other LED's.
