Trimming BL602 build for ota on the Sonoff B05-BL bulb. #473

Closed protectivedad closed 1 year ago

protectivedad commented 1 year ago

The OpenBL602 image is too big to send OTA to the Sonoff B05-BL-A19 bulb.

First I am not even sure it can be upgraded using the OTA. The Sonoff website says it can but I haven't tried it since I have no firmware small enough that would allow me to do it. After looking at the SDK ansd trying things like nuttx I have concluded that my best bet is to trim down the OpenBL602 build. Since I have found things that I think are redundant I figured it would be helpful if I generated PRs as I did them.

I'm fairly new to the PR process but I'll try. I opened this report just to get feed back and suggestions. I'm not sure how to tie together PRs for the OpenBL602 repository.

recommend starting with the map file, if the build makes one. Also, Alpha has had a lot of text cut out. BUT... it's under suspicion of causing death on N at the moment... you could safely cherrypick the getcommands commits, I think, which remove descriptive text from source, and put it in .md files.

@protectivedad Hi, I'm sorry for bothering you Were you able to flash it using DIY mode successfully? I'm afraid that i might brick mine and i don't have the required tools to flash it using UART.

I didn't my gaze was drawn away elsewhere. I did use the great youtube video provided by "Elektroda com" to dismantle the bulbs in a non destructive way and flash via UART. I don't think I have any original bulbs around to test. Sorry.
