Is esp-link compatible with ESP WROOM 02 ? #395

Closed stramike closed 5 years ago

stramike commented 6 years ago

Hey there! I know esp-link is not compatible with esp32, but what about this ESP WROOM 02? datasheet in the link below: https://uk.rs-online.com/web/p/wlan-modules/1359766/ It doesn't have bluetooth like ESP32, and it integrates the ESP8266EX WiFi chip (is it like a new version of the ESP8266?).

Thanks for any help!

You can try, it's 32Mbit flash

stramike commented 5 years ago

Thanks for the very quick reply! I'm ordering one to try it! As soon as I get it I'll tryit and report here if it is compatible.

Hi. @stramike did you manage to test esp-link in ESP WROOM 02?

Anyone get this working?

uzi18 commented 4 years ago

It should, but what is your problem? Is it 4Mbit = 512kB flash?

agrieco commented 4 years ago

It is not 'just working' for me so before I dug into it, I figured I'd check and make sure it should be. Will take a closer look. thx

one problem could be here - small flash

agrieco commented 4 years ago

Yea- I can't get it to work....but am also a noob. Could you suggest the appropriate/proposed set of esptool options I could try? I've been using different flavors of..:

esp-link-v2.2.3 # esptool.py --port /dev/tty.SLAB_USBtoUART --baud 115200 write_flash -fs 32m -ff 80m 0x00000 boot_v1.5.bin 0x1000 user1.bin 0x3FE000 blank.bin
