Re: INPUT state of Open Drain OUTPUT

External pullup doesn't seem to help either.

Re: INPUT state of Open Drain OUTPUT

I'm not switching to INPUT as none of the examples I've seen for the ESP8266 do that. They simply read it as if it were an INPUT. I'll try the external pullup next

INPUT state of Open Drain OUTPUT

This is pushing the limits on my MCU/GPIO knowledge so sorry if I'm missing something obvious. I'm trying to port an i2c bit-banging library but I cannot seem to get it to read the pin state. My understanding is that configuring the GPIO as an Open Drain OUTPUT with the Pull Up resistor enabled shou...

Re: jump to run addr @ 0x40000

@johnlee the 103mA was idle after boot. I only have a handheld multimeter so I cannot take more accurate measurements at the moment.

Re: user code done

No more progress but there is a clear distinction between using -fs 2m/4m.

If I do not include -fs or use -fs 4m (same thing) I get stuck at "jump to run addr @ 0x40000"

If I use -fs 2m I get there "user code done" message.

Re: user code done

I made a little progress this morning. Changing the blank.bin address from 0xFE000 to 0xFC000 does not seem to have helped, but dropping -fs and letting esptool32 default to 4m helped some what. It now progresses to " jump to run addr @ 0x40000 " but is back to the problem in my post of the same tit...

Re: jump to run addr @ 0x40000

David?! Whatever...

Yes, the multimeter is indicating consumption of just over 100mA most of the time.
Anyhow.. this isn't my biggest issue at the moment.

Re: jump to run addr @ 0x40000

This could possible be a power supply issue. I haven't change anything there, but when I have the power running through my multimeter it boots reliably. Idles ~103mA

Re: jump to run addr @ 0x40000

Sometimes the garbage out put is different, or nothing is output after 0x40000.
Occasionally I will also see a reboot with cause: 12
