error trying to make blended-rectangle from chap. 9 of IOT dev book

[bap293]

I am getting this error when building blended-rectangle from chap. 9 of IOT dev book. The hello world gui example works fine.

It looks like you may have tried to run the blended-rectangle example using mcconfig instead of mcrun. That would fail, perhaps in the way you show.

The process is described in the section "Running Examples" starting on page 12. In short, to run the blended-rectangle example:

1. Build and install the Poco Host 9 (ch9-poco/host) using mcconfig -d -m -p esp32/moddable_two. (See pages 357-8)
2. Buitd and install the blended-rectangle example (ch9-poco/blended-rectangle) using mcrun -d -m -p esp32/moddable_two (See page 13)

Host applied successfully via mcconfig.

But error on mcrun:

C:\Users\Bill\projects\iot-product-dev-book\ch9-poco\blended-rectangle>mcrun -d -m -p esp32/moddable_two

Stop.

If I follow the instructions, everything works correctly. I'm using the current Moddable SDK and a Moddable Two.

I am able to duplicate the error you report if I install the wrong host. Is it possible that you didn't install the Chapter 9 host, or perhaps you installed another host over it after? On your PC Chapter 9 host is at C:\Users\Bill\projects\iot-product-dev-book\ch9-poco\host. When you install the host, it traces the following in the xsbug console:

I tried it again, same thing.
Is there a way to verify my setup?

I am tempted to rebuild the whole thing from the ground up. I've got a decent windows 7 machine (current machine is win 10 - where the setup is now.)

I do get the "device flashed" message after the host install.

In case this matters - here is my process: after installing the host, I ctrl-c twice to get back to a cmd prompt, then I do the mcrun on the blended rectangle (I do not close xsbug during this process).

Thank you so much for helping - I had a good career in software dev. (now retired) - and I tend not to give up. I've got some ideas for this platform.

Rebuilt entire toolchain and SDK. Same issue.
Wondering if we are on different versions of toolchain, sdk or example code.
I am on Esp-idf 4.3 (note: the espressif version, not the one Moddable-OpenSource/esp-idf version); default branch (Public) of Moddable SDK; appears to be only a master branch for the book examples, so I am reasonably certain I am up to date there.

One possible difference is that I am on Win 10.

Windows 10 should be fine; that's where I develop and test the Windows build.

@bap293: what device are you using? The symptoms you're seeing can sometimes crop up when we don't have the correct baud rate set for the device. But that shouldn't be an issue with, e.g., a Moddable Two.

One other thing that's worth trying is erasing the ESP32's flash storage. Sometimes you can get stuck in an odd state and erasing can fix the problem. You can do that with:

python %IDF_PATH%\components\esptool_py\esptool\esptool.py erase_flash

[bap293]

I erased the flash (thanks for that info. - was wanting to be able to do that).
Same error during mcrun as above.

I am using the moddable-two

I am able to run the moddable examples that only use mcconfig - I just can't get the ones from the iot dev book that need the mcrun command after loading the host.

One thing to note: I get a missing file error at the end of the flashing o]f the host: Leaving...
Hard resetting via RTS pin...

i noticed this after I rebuilt the toolchain.

Is it worth rebuilding the tool chain using this: from git: the esp-idf
