Thank you very much! In the supplied link, I don't understand the final numbers in the various uart image files like 800_800, 600_600. Is this some sort of screen resolution or something? I have the V5 which I understand means I have DDR3 memory and the label of 1G indicates that I have 1G memory and by viewing the board and seeing the dual chips, that narrows down my selection to the 2CS version. The question is, what do the dual numbers following that mean, and how do I know which to select? Thanks!
I suspect it's some kind of clock speed
Yes, it is the bus speed !
Lowest = more stable but less fast...
Well unfortunately something else must be hosed. After several syntax attempts I finally came up with one that worked. Note that the command is changed since I put all my install files and the command file in the same directory. I successfully loaded the files from the 600 library or the slowest bus speed ...

Now once this completed, I would assume that re-plugging the device from UART mode back to standard as it was shipped would give me something new on the console. It didn't. I got the same old ">" and "E" that I had before....

I just checked Globalscape to see if maybe my board is still in warranty. LOL 30 days - that's thirty days LOL.
after you have booted by uart, you need to flash again the bootloader...
uard mode is just for load and booting, not flashing...
you may use also the fresh uboot from openwrt : here ->
the trusted firmware folders contains UART boot files and flashable uboot

... and then use UBOOT command to fix MAC and BOOTCMD ...
Did you see that
a) my console will not connect or display when the board is plugged to UART mode
b) the process completes successfully after the command:
./WtpDownload_linux -P UART -C 0 -R 115200 -B ./TIM_ATF.bin -I ./wtmi_h.bin -I ./boot-image_h.bin -E && minicom -D /dev/ttyUSB0
c) the console software will still not connect when board plugged to UART mode
d) returning to SPI mode shows the same condition on the console with no indication that UBOOT is running.
I don't understand, the last thing you posted was Uboot saying:

This is a message from U-boot telling you it's about to boot. So what is it that you are having issues with?
You have to interrupt the uboot when and just after it is loaded by UART, then you have to reflash uboot with bubt command line... and only then you can access your uboot from SPI booting...
Look inside my logs, in the HOWTO, all commands are shown

>E
is correct when the bootloader is corrupt, your console is working
PS : take care to remove hardware handshake in the minicom options !
Do you have uboot starting up ?
Can you interrupt the boot ?
UART is just for loading so you may had the uboot starting from memory !
Need to be flashed correctly

UBOOT means something on the console except E and >, is this correct?
The problem is that before the UART load I see E and > from the console and after the UART load completes successfully, I also see only E and > on the console. There is no Marvel command line or anything like in the documentation. ANd each time I press the ENTER key it changes from E to > and back to E and back to >. If I press the reset button on the board, each time I press the reset button the number of arrows grow. For example if I press the reset button 4 times, the console will appear >>>>
I do not under stand the order. PRESS A KEY AT UBOOT BOOTING
- with board plugged to UART, the console will not connect
- the command Wtptp..... is loaded from the Linux terminal window
- the command completes.
- you say here to PRESS A KEY AT UBOOT BOOTING
- I cannot see UBOOT if I do not have an active console session, is this not correct?
- I must replug to SPI mode correct to get the console?
- when I did this before, there was as if I had done nothing and the console was still corrupt
After this command finishes on my laptop Linux distribution, then what?
Do I use minicon at that very moment, without re-plugging the board to something other than UART?
What parameter are you suggesting and how to I set that up, I have not used minicon before.
How can minicon connect if still in UART mode?
This command will execute minicom to USB console at the end of WTPDownload and will give you access to the system, so if you KEYPRESS at the UBOOT loading (the one loaded and started by WTPDownload) you then be able to BUBT (flash uboot) and repair/recover/rescue your EspressoBin !
You only change the bootmode to UART from SPI to get this possibility of loading uboot into memory with WTPDownload...
You will only get back to SPI mode from UART mode when you will have successfully repair/reflash a ne uboot to NOR (SPI) with the BUBT command
You will always get ">" from UART MODE, but get a "=>" or "Marvell >", depending of the uboot version, from uboot...
The objective of the method of recovery is to load into memory a UART version of UBOOT...
This will be temporary, because it's not flashed but only loaded in memory, so a RESET or a POWERCYCLE will empty memory back...

yes
you need to do a CTRL+A and CTRL+Z and then go to O (options), then serial port config, then disable Hardware Handshake (F)...
If not done, your console will not get keypress from your keyboard !!!

Then you can save to default settings (if not, you'll need to redo these options configuration at net minicom usage)...
You must do all the process of powercycle, plug wtpdownload && minicom if you get not access to UBOOT, or if WTPDownload is not successfull...
Yes, need minicom to be started as fast as possible and KEYPRESS be send to the EBIN to interrupt UBOOT loading...
No !
Not before you have recover / reflash a new version to your EBIN NOR MEMORY...
WTPDownload is not permanent...

You may get "=>" or "Marvell >" depends of the version of uboot you load...

Got it. yeah, a little hard to follow. I'm glad I never got into this situation with my espressobin... I guess there's a reason i'm sticking to RPi these days and it's to avoid this kind of loss of time. I mean, I spend enough time tinkering with small computers as it is!
