General guide for porting/installing on standalone ARM proc?

Is there any sort of guide or documentation to assist with installing MicroPython on a stand alone ARM processor? I'm not sure where or how to start. I realize it's a fairly broad and general question. I'm not asking for specifics here, rather a pointer to any preexisting writing on the subject, if ...

Re: Batch of 5X ESP-01S won't boot

IT WORKED! Your command differed from mine in two ways. It explicitly stated the firmware size and it indicated a different firmware mode. So I tried it again, reverting each of those parts to my original command, and the part that is relevant is the -fm change. I can still use --flash_size=detect a...

Batch of 5X ESP-01S won't boot

I just bought five ESP-01S boards in a batch, so they're all identical. esptool had no trouble erasing them or writing firmware to them, but when I restart them in UART mode, all I get is the usual single brief LED wink. No terminal REPL and no MicroPythonXXX wifi network. These are 1MB boards. I ha...

U.S. availability

PyBoard D is only listed on the official store, based in the UK. The international distributors, such as Adafruit, Sparkfun, and RobotShop don't list the D on their websites, only the v1.1. Can the D only be obtained from the UK?

Thanks.

time.sleep() vs machine.lightsleep()

Is time.sleep() (or utime.sleep()) the same thing as machine.lightsleep()? They take slightly different arguments (float seconds vs. int milliseconds), but functionally are they doing the same thing? Is there a recommendation between the two? Are the functions under the machine module meant to suppl...

Re: D1 Clones

All right, so yours is working. Thanks. I have two completely different D1 minis (both clones, I admit) and both suffer a fairly widely experienced problem in this regard. Waking with an alarm just doesn't work. Hard resetting works, and resetting from the "zombie" state of an erroneous alarm wakeup...

Re: How to use a low-signaling sensor to trigger wake interrupt

Yes, sorry. I see your point. I did write that. I was referring to the only "logic" connection, pushing aside the issue of actually powering the sensor, and furthermore that ground should be "common" amongst components. But you are right that such details need to be clarified.

Thanks!
