Hello,
I have a bunch of ESP8266 Huzzah's. I followed Adafruit's tutorials (LED Blink and simple Web client) (https://learn.adafruit.com/adafruit-huz ... rduino-ide) and they worked just fine (using Arduino 1.6.6). But the next morning I repeated the same steps but the code didn't upload - the blue LED merely blinked for 5 times then I got this error:
So then I discovered esptool.py and that seems to work only 1 out of 10 times. The one time it does work, however, the Huzzah spits out its innards in a massive memory hex dump, plus wdt reset stuff:
and:
I'm using an FTDI cable and plugging it to the USB port on my laptop - I don't know if that is relevant. Also, on the hpclab page, the command unnecessarily includes
a write command to 0x10000 which I think may be the issue here (Memory map). I inadvertently executed this command to write to 0x10000 (because it was in the damn tutorial! WHY IS IT EVEN THERE!). I don't know if that has corrupted some region of memory or something.
I then found out about some (dubious looking flasher tool), but the instructions are close to useless - as in which bin file to write to which memory location, and I can't figure out what to do even though I have the memory map information.
PLEASE HELP!

I'm using an FTDI cable and plugging it to the USB port on my laptop - I don't know if that is relevant. Also, on the hpclab page, the command unnecessarily includes
Code: Select all
write_flash 0x00000 "{build.path}/{build.project_name}_00000.bin" 0x10000 "build.path}/{build.project_name}_10000.bin"a write command to 0x10000 which I think may be the issue here (Memory map). I inadvertently executed this command to write to 0x10000 (because it was in the damn tutorial! WHY IS IT EVEN THERE!). I don't know if that has corrupted some region of memory or something.
I then found out about some (dubious looking flasher tool), but the instructions are close to useless - as in which bin file to write to which memory location, and I can't figure out what to do even though I have the memory map information.
PLEASE HELP!
