Problem with 2017.07 U-Boot for SheevaPlug

After installing the new 2017.07 U-Boot on a SheevaPlug I was having trouble booting and I discovered the issue is a missing "load" command.

Ray,

Power up, interrupt serial consle and,

help

Then post the entire serial console log up to this point.

Hi Ray,

Thanks for reporting this problem. Indeed, the mainline code does not have load command. And I missed this patch (for the Sheevaplug only :) Other boxes should be OK.

This load command was available to all Marvell plugs. However, at some point in mainline someone mistakenly removed it from Sheevaplug (indirectly). So I need to patch it back.

Please test this version (attached).

You can kwboot it, change the u-boot envs back to use "load", and then boot.

Since I can't get access to my Sheevaplug now, could someone test this u-boot image uboot.2017.07-tld-2.sheevaplug.mtd0.kwb attached above?

Thanks!

Bodhi, the Sheevaplug is one of the units that does not support kwboot. However since I have multiple Sheevaplugs and a JTAG unit I have tested with the following results:

Note the load command is now present! And I even tested for confirmation:

Sheevaplug> load $bootdev $device $load_dtb_addr $dtb_file
10506 bytes read in 35 ms (293 KiB/s)

So I believe it is safe to publish this version as the latest correct image for the Sheevaplug.

Thank you,
Ray

Yes I've mixed this up with the Dreamplug!

Apologies for this unrelated post... You mention a JTAG unit.. What are they?
I've heard of them but no idea what they really are and wondered if I could use one to access my GoFlexHome unit, which has stopped responding to kwboot and shows no sign of life after a recent U-Boot flash.

Some of the Sheevaplug units come with a built in microUSB port that exposes serial and JTAG. I also have a GuruPlug JTAG Board that is still listed for sale at GlobalScale's website for $39. I got lucky on ebay and acquired a couple of GlobalScale Dreamplugs that came with the JTAG boards. There are other JTAG boards that would work and there are even instructions available elsewhere on using the GPIO output of a Raspberry PI for JTAG.

This is my favorite JTAG info from ReDox

As I and feas have mentioned several times, before you flash u-boot, post the commands here for review before you actually doing it. You probably had a typo somewhere.

That's better.

Not knowing anything about JTAG I have no idea about what this means:

Connect the BusPirate and the Serial Adapter to the Dockstar's JTAG header

Does the GoFlexHome have a JTAG header? I don't know what to look for... Are there any pictures/diagrams which illustrate how to make this connection?

I have no pic for GF Home.

Buy here is a good pic for iConnect:
https://wiki.openwrt.org/toh/iomega/iconnect

All these Marvell plugs JTAG header are more less identical, which is a standard ARM JTAG 20 pin.

Here's a picture of a GoFlexHome base unit:

https://images.anandtech.com/doci/3955/baseunitinside_575px.jpg

I don't see anything like that shown above, only the 10 pin holes where I connect the serial adapter in the bottom right hand corner.
