Issue uploading custom Tasmota firmware

[danielvega3009]

Hi,

I have modified the tasmota firmware to include a new functionality for a personal project, when uploading the firmware to my tasmota device from the application, it gives me the following error:

How could I flash my tasmota device?? without welding please.

If you see the message "upload buffer miscompare" means not enough space. Please, use minimal or lite and then use the full version you want.

... the problem is that after uploading my firmware I noticed that now the tasmota application was very slow ...

I'm sorry but as it is your own custom version, we don't know what you have changed hence we can not help you. If you have used delays or blocked loops, your modified version won't work. So, about upgrading, we can help, but why your own firmware does not work, we can't as we don't have it. Sorry

my custom version is exactly like the last version of Tasmota in Github, but I added a new function that when the device connect to wifi, the device does a query a database to check if the device is registered in the network, because I have a local network where every device sign up automatically in a data base, only that, this code was added in the xdrv_01_webserver.ino file into the StartWebserver function

@barbudor my device is athom smart plug based in tasmota https://es.athom.tech/blank-1/color-smart-plug

Your change may seems small to you eyes but it may impact Tasmota event loop.
I suggest restarting from original code and adding pieces of code one by one to idendity which piece creates the problem
