Huzzah Lua Reflash Problem

Post by Nick224 »

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 ?

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

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.
