D2WD works well:

have a look here in this thread and this postings

hope this helps further

and please
post the reset reset reset log - this helps us to find out what's going wrong and why.


perhabs you can start simply the read ID prozess
can you communicate with the eMbeddedFlash?

example ( use the newer esptool version please )

Code: Select all

make flash_id
hello word
esptool.py v2.0-beta3
Connecting........____
Detecting chip type... ESP32
Uploading stub...
Running stub...
Stub running...
Manufacturer: 9d
Device: 7015
Hard resetting...

thank you

Thank you! I will try it as you say, but i want to ask if we can supply the esp32 d2wd in 2.8V@200ma? Because the ldo we select work in this voltage and ampere. Apart from you use the lab power supply, we use a battery and ldo to supply power for the esp32 d2wd.Can you suggest some suggestion for the esp32 d2wd? We are disapponited that when we supply the esp32 d2wd 3.5V 3.6V by the dc source but the chip reset reset and reset.But when we just provide the voltage 3.3v the d2wd can work well.
Thank you a lot. :D :D :D

I think you should test the chip esp32 d2wd , when you supply the voltage over 3.3v the chip will reset reset and reset.

i think there is a big missunderstood here.

first:

the D2WD works very well in the supply 2.3 - 3.6V itself.

BUT

cause D2WD has eMbeddedFlash inside for your firmware,
and this eMbeddedFlash is working only with 1.8 V
and this 1.8 V comes from intern Reguldator of the D2WD ( named VDD_SDIO )
you must set the bootstrap pin "MTDI " high for D2WD
this means, you must connect the "MTDI" pulled up to 3.3V


if you use the flash download tool 3.4.9.2it supported D2WD


but backto your reset resest reset


please post the log for this - there are some infos in the log what is going wrong.
can you please post your reset reset reset log
thank you

best wishes

could you please offer the demo board of esp32-d2wd,or how could we get or buy the demo of esp32-dwd?
below is the reset compare to the normal log,please check the problem as soon as possible?
we confirmed that VDD_SDIO is 1.8V,and already pulled high for the pin of MTDI.

I see you are configuring some GPIOs... which one do you configure after GPIO10?

After configure GPIO10.GPIO is not configured any more.After configure GPIO10,"periph_module_enable(PERIPH_I2S0_MODULE)" is called.The followings is reset log and the dump file using "xtensa-esp32-elf-objdump -D -S developing.elf>dump".Could you please give us some suggestions by checking reset log and dump file?

Also,
Thank you! I will try it as you say, but i want to ask if we can supply the esp32 d2wd in 2.8V@200ma?
That is not going to work. We recommend at least a 500mA power supply for the ESP32 in our design guidelines.

So it must be at least 500ma power supply for the esp32? But why we try it can work in 2.8V-3.3V, and 3.3-3.6V the d2wd would be reset reset reset? The d2wd can work onetime and why it may resset reset reset another time? Is it the current too short cause the problem?

Sorry, but this is wild goose chase unless you post schematic, source code, and exact steps to cause crash.
