Re: NON-OS 1.5.4 (16_05_20) PWM bug

I note you are using RBOOT - are you now having issues with RBOOT on new devices from around 1.54 onwards? I am having issues - the software is not starting up in the right order and sometimes not at all - all started around 1.54 It shouldn't be too hard to reproduce. Connect PWM channels to io 14 a...

ESPTOOL and WRITE PROTECT

#i and others are having a lot of trouble since changes to the SDK around 1.5.4 - and part of that is to do with FLASH. Am I right in saying that this c:/espressif/utils/esptool.exe -p COM3 -b 115200 erase_flash Should erase let's say the 4MB FLASH (32Mbit) on an ESP12 INCLUDING the system parameter...

Re: Dead ESP

The problem I reported in 1.54 is still there in 2.0 RBOOT or rather a program using RBOOT is not booting up correctly. Messages at powerup are not coming up in the right order. Notice below - some simple informative text at the beginning.. with ~ESP Starting- and about 7 lines down, "Station m...

【Feedback】Parameter area write protect

I've been having some issues with boards and recently discovered an issue with the SDK 1.5.4 and RBOOT... that is covered elsewhere. In the process I've had more than one board ending up booting (at 78k) with a parameter area issue. In an ESP12 that is typically right at the top of the 4 Meg. Using ...

Re: [ESP8266] I2C_Demo

Call me slow but I came looking for an example of I2c - and there's a NONOS file - with everything BUT an example of I2c - am I missing something? I'm having trouble - I have an ESP8266 talking to Arduino. The ESP can send multiple bytes to the Arduino - no problem - but I haven't a clue how to get ...

Re: Dead ESP

Pleas DO come back to me on this - RBOOT is well used out there - and we put a lot of work into understanding how to use it. It's ok to say the latest version is ok if you use Espressif boot binary - but that's a big learning curve - in software that has worked for many months... I think I'd rather ...

Re: Dead ESP

Hi there I'm a little further on - this ONLY happens with SDK 1.5.4 - return to 1.5.3 and the problem disappears completely. I have an idea that something has changed in 1.5.4 that is making Richard Burton's RBOOT fail given a totally blank FLASH. It took me a while to come to this conclusion, as ru...

Re: Dead ESP

Hi there Pratik Ok, so I'm using the ROMS from my site - http://www.scargill.net http://www.scargill.net/rboot.bin http://www.scargill.net/romx.bin These should be blown at 0x0000 and 0x2000 respectively. The board should boot up and start looking for an access point at 115k baud. This assumes any E...

Dead ESP

Not sure if you'd describe this as a bug - but I'm hoping it will reach an Espressif engineer or someone really familiar with the devices. ESP-12 - doesn't really matter which device - but an ESP with 4Meg of RAM. We have software which uses the SDK - and is now fairly big at just over 0.6 meg. We u...
