Hello,
I used NodeMCU Firmware Programmer to rewrite Lua into my ESP but there's a problem.
So...these are my settings:
-Baudrate: 115200
-Flash size: 4 MB
-Flash speed: 80MHz
-SPI Mode: DIO
-INTERNAL://NODEMCU
-ADDR: 0x00000
-Flasher: RS232 <--> USB
Baudrate, size and speed from Arduino IDE default config, SPI Mode from MCU Programmer.
According to the Programmer, everything went ok but I'm getting message like this:
Am I doing something wrong ?

Re: Huzzah Lua Reflash Problem
we use the nodemcu loader and works great, when we need it (the modules do come with Lua already burned in)
only thing to check is make sure you have a good USB to serial converter
RS232 is a +-10v protocol, you need to use an FTDI cable or similar, with a genuine chip, knockoff adapters and low voltage lines cause a lot of problems

Re: Huzzah Lua Reflash Problem
I'm using RS232 with UART lanes working at 5V and I used logic level converter for 3.3V.
Arduino programs are working (almost) good but I get random restarts like in THIS video.
But I need LUA, it's easier.
