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

Re: [Tool Release] FLASH_DOWNLOAD_TOOL
Ok, got Windows all set up with an example "hello world" - compiles just great... not the foggiest So what is the equivalent on the demo board (the kit we received with the ESP32 board and 0.1" spacing base board. Which pins on that board need to go where??? Has anyone already programmed the chip -...

jump to run addr @ 0x40000
I've made a ton of progress so far. Having got my dev env setup before the module arrive, I'm not compiling and uploading code. The problem I'm currently facing is the issue of the device generally not wanting to boot. 9 out of 10 times I get stuck with this. jump to run addr.png If I keep rebooting...
