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.

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 ...

CC3200 build environment

After reviewing the readme, I should be able to build firmware for the WiPy1 and CC3200 Launchpad using the toolchain from gcc-arm-embedded and it certainly seems to work most of the way ... builds complete with no errors and the board is mostly functional. I can't get the builtin FTP server working...

Re: I2C baudrate oddity?

9600 seems like a very slow clock rate for I2C, is this an asynchronous (ie RS232) device ? I suppose there is probably an I2C UART that will do the job for you but I suspect you weren't intending that ...

I'm unclear what you are refering to ... ftp server or telnet console ?

Reflash via jtag ?

I have a wipy which only boots in full safemode, the sense GPIO probably stuck high (in hindsight that simple jumper for safe mode was too simple :-/ ... has anyone had success reflashing the bootloader ? I'm thinking if I remap the safe mode pin the board could be used again.
