Hello.
Has anyone happened to flash the board as shown in the pictures?
Girier socket with voltage measurement, freshly taken out of the parcel box straight from the far east.
https://pl.aliexpress.com/item/1005008248987558.html
According to my measurements it came out that the connection of the programmer is as follows:
I connected via putty under COM4 at speed 921000 and I get some messages from the device, that is, it can be assumed that RX/TX are connected correctly.
When the potential Boot (GPIOA9 according to the chip's schematic) is connected under GND, the default Wi-Fi does not show up and the putty is silent.
Yet when I close putty and want to download myself the firmware, I get an error:
My board looks twinned with the WB02A:
Except that it doesn't work.
I have run out of ideas.
I am counting on you.
EDIT:
I've taken a snapshot of what putty shows when the socket gets up
interestingly, it stopped showing me that default wifi....
"GPIOA_9 high level, will enter Normal mode!" meaning according to the schematic the 17th leg on the chip.... and this is the one according to the multimeter that is connected under GND at my place, then putty is silent, but python shows no transition to download mode
