New firmware release 1.6.9.b1 (frozen code support and framebuf)

[robert-hh]

@daniel Thanks, it works.

[daniel]

@Butch, this firmware release is pretty much the same as before 1.6.8.b2 only that it adds 8KB of extra heap. Can you try a safe boot, format the file system of the problematic LoPy and put the scripts back again after a normal reset?

[daniel]

@robert-hh thanks, the problem when checking out was due to the default branch not being master. I have just fixed that and also pushed the commit that bumps the firmware version to 1.6.9.b1.

Hi @daniel , it looks like you are juggling with too many versions. The one that compiles at the end from the pycom-micropython-sigfox repository is 1.6.8.b1, however with frozen code support and framebuf).

>>> uos.uname()
(sysname='LoPy', nodename='LoPy', release='1.6.8.b1', version='b8220c0-dirty on 2017-03-24', machine='LoPy with ESP32', lorawan='1.0.0')

And I could see that adding the line:
#define MICROPY_PERSISTENT_CODE_LOAD (1)
indeed enables executing .mpy files from the file system.

Following up on my on reply, here's some additional information. If I connect to the LoPy and boot, here's what I see:

And then it just hangs there. This is the LoPy previously configured with LoRa Nano gateway code.

The other LoPy, previously configured with LoRa Nano node code and updated to the same firmware version as the gateway, shows the following output on boot:

As you can see, I get a repl and can verify the version of firmware installed.

Any ideas?

Thanks!

@daniel I updated my firmware yesterday afternoon to 1.6.8b2 (I think), and that solved my LoRa problem and all was good. This morning, I updated to 1.6.9b1 and I can not longer run the code:

$ pyboard --device /dev/cu.usbserial-DO003AJF --baudrate 115200 LoRaNanoGateway.py
b'\r\n>>> \r\n>>> \r\n>>> '
could not enter raw repl

It seems like something has gone awry with talking to a "friendly" or "raw" repl.

Suggestions?

Thanks!

Hello @daniel,

I would expected that it now supports externally pre-compiled code (.mpy files) from the file system to, but it does not. That would only need the statement
#define MICROPY_PERSISTENT_CODE_LOAD (1)
in mpconfigport.h.

Hello @daniel. The links lead to a repository pycom-micropython-sigfox, which cannot be cloned. Error: HEAD refers to a non.existing external repository.
It looks like it is assuming a very specific repository structure.
Update:
found a way: I had to clone the branch "github"

[robert-hh]

Brilliant. Can' t wait to upload it.
