Re: Nucleo re-programming problem
I had already updated both stlink (v1.5.1-12-g30de1b3) and the programmer bootloader (V2J33M25) but I tried the suggested commit (358a913) as well ... no change, still get FAIL.TXT and nothing on st-info --probe ... :( I guess something else is going on, will have to dig some more. On the bright sid...

Nucleo re-programming problem
I have a Nucleo-L476RG board I have successfully built and programmed with Micropython (REPL is running via CDC etc.) however I have been unable to reprogram it since ... it appears the ST-link interface can no longer access the stm32l476 anymore, the MBED drive now has a file FAIL.TXT containing 'T...

Re: [STM32L476DISCO] RTC not ticking
Many thanks for pointing out the init() function and that it needs to be called explicitly ... I couldn't figure out why the clock wasn't running on my board (based on the Nucleo-L476RG port) unless I had already run some other code (using CubeMX) that had initialized access to the RTC backup regist...

Re: Mount SD card later in my program using os.mount
I have a similar application, want to use SD for datalog only, not code. When I try this with the latest though (1.9.4) I get >>> sd = pyb.SDCard() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute 'SDCard' so clearly not defined ...

Re: webrepl_setp throws OSError: [Errno 2] ENOENT
Bringing up a fresh esp12 module with micropython, latest from git, looks like a similar problem but the module has a 32 Mbit memory so that isn't the issue. it doesn't appear to be setting up the filesystem initially and (likely as a consequence) I can't get webrepl_setup going. It took a few tries...

WiPy 1.0 filesystem reset
Still struggling with my WIPy 1.0 running 1.9.3, it does not appear to be reading the boot.py or main.py scripts on startup. The files appear OK via ftp but were left over from earlier versions so I tried resetting the flash file system. The recipe as documented doesn't work ( http://docs.micropytho...

WiPy 1.0 and I2C ?
Returning to my WiPy I've been struggling getting the I2C talking to a sensor ... has anyone got theirs working ? After updating to the latest 1.9.3 I managed to initialize the port but scans are intermittent (even at low speeds of 1 kHz) and reads of even 1 byte give EOI errors. The I2C sensors hav...

ESP8266 RTC memory ?
Is there any MicroPython mechanism for using the RTC memory on the ESP8266 ? Or is it already in use internally ? I'd like to retain some values between deep sleeps. (didn't find anything in the documentation).
thx.
thx.

Re: Support for 512K modules reinstated
Just playing around with a couple ESP-01 at the moment and noticed a 512k make target ... it doesn't seem to do much and certainly doesn't deploy, is this intended to work ? So far I can load a daily build from downloads but not make my own.
Any hints appreciated, thanks.

Re: CC3200 build environment
Bingo, problem found ... you are using a considerably older gcc version (4.8.4) compared to what I have (6.2.1). When I revert to gcc 4.8.4, ftp works, while the same tree built with 6.2.1 doesn't. I'll try to track down where the breakage starts then dig deeper, could be a compiler bug or a latent ...
