Re: Understanding the difference between bootloaders mboot and hw dfu

Dave,

You made my day!!

I were about to just go ahead and design a custom hardware based on USB HS DFU.

Thanks for pointing this out!!

Understanding the difference between bootloaders mboot and hw dfu

Hello Everyone!!

My question may be wrong. If so please point it out.

Why would we need a boot-loader stuff like mboot, while the stm32 controllers by themselves are factory programmed with hw DFU boot-loader.

Thanks in advance!!

Re: BMI160 9DOF IMU with pyboardV11

Thank you so much for getting back so quick!!

That was pretty interesting :P .

I have been looking to use the IMU part alone. I may even use the env sensor later.

Would you be able to suggest on any break-out boards to start off with ??

BMI160 9DOF IMU with pyboardV11

Hello Everyone!! I have been trying to find out a 9DOF IMU to interface with the Pyboard(V1.1) that I have been playing around and planning to give a try on BMI160 IMU from Bosch. Has anyone given a try so far with this or any kind of 9DOF IMUs? I am planning to use this library https://github.com/m...

Re: iap in micropython?

Hi Dave How could I split the internal flash memory into two banks(one for existing firmware and another for backup). I might need to do this specifically in case if I need to go for remote firmware upload with the help of a gsm module. What if I download the firmware from remote server , place it i...

Re: custom library - fota for non networked devices

Thanks for the quick reply there!! :)

As of now , the only way of networking is to use the GSM module(project specific). :roll:

I not sure whether I could use any other module to get this done :|

Re: custom library - fota for non networked devices

The term non-networked which I referred was the factory state of the device. Like ESP8266 which is Wi-Fi enabled(networked) by default, PyBoard is not. I am planning to use an external cellular engine. Coming across various forums, I find that the typical way of doing this is to maintain two banks i...

Official documentation on the MicroPython Language Architecture??

Hello Everyone!! I have been exploring micropython on PyboardV1.1 and it's been a while. Right now , I have been trying to understand :? the architecture of the whole project/repo/language(excuse me for this notion, since I'm not sure on how to call this) and at some point in time it might happen fo...

Re: Q: Where to put main.py in Custom Firmware?

[quote=Roberthh post_id=11945 time=1468222217 user_id=601] main.py is a proper place to put your start code in. That resides in the flash file system. If you prefer to have it in the scripts folder, which moves into the frozen files space, then you have to change esp8266/main.c and rebuild. But both...
