make flash errors

[tony2simmy]

In MSYS32, 'make app' works well. When i want to download the program to ESP32，executing command 'make flash'. But some errors happen.
Flashing binaries to serial port /dev/ttyS22 (app at offset 0x10000)...

I guess it may be the problem of configuration , don't know how to solve it.

Are you starting mingw32 or msys2 prompt?
It should be mingw32 in order to use Windows port names.

It should be mingw32 in order to use Windows port names.

I start with mingw32.exe but my system is 64 bit.

You cant find a com port, are you using the correct COM port? 23 seems high.

serial.serialutil.SerialException: could not open port '/??/COM23': WindowsError (123, 'The filename, directory name, or volume label syntax is incorrect.')

You can also try addressing the /dev/ttyS*
In msys2 type ls -la /dev/ | grep ttyS

for me this outputs:

Code: Select all

schr0015@DESKTOP-NB6H7MP MSYS ~
$ ls -la /dev | grep ttyS
crw-rw-rw- 1 schr0015 Domain Users 117,   0 Jun 20 13:23 ttyS0
crw-rw-rw- 1 schr0015 Domain Users 117,   3 Jun 20 13:23 ttyS3

ttyS3 would be my ESP32.
Set that in "make menuconfig"
"Serial flasher config" -> "Default serial port"
/dev/ttyS3

Use windows port names in menuconfig such as "COM23"

Hi f.h-fs,
Please see the below log:
"Flashing binaries to serial port /dev/ttyS22 (app at offset 0x10000)..."
I had changed the com port number. ttyS22 is my ESP32.

1.Download MSYS2.
You can get it from https://dl.espressif.com/dl/esp32_win32 ... 170330.zip
2.Extract it.
Extract the file of compressed from directory that you have chosen in previous step.
3.Run MSYS2 .
Double click ‘msys2_shell.cmd’.
4.Install tools in MSYS2.
Install python,pip,pyserial.

ttyS22 is pretty high and can be equivalent to com23 in windows. like f.h-f.s said, try ls -la /dev/ | grep ttyS command and see what port you have open. Or maybe you have running putty or other serial program on this port.

EDIT: Just checked with my config, ls -la /dev/ | grep ttyS shows me /dev/ttyS2, but i got same message as you when im using it in menuconfig. With com3 all is fine.

$ make -j3 flash

The version of Python we ship is not actually an MSYS2 Python, it's a MinGW python. So it doesn't ever recognise paths of the form "/dev/ttyXX". Use "COMxx" instead, same as for a normal Windows program.

(Unfortunately the only options we have for Windows Python/pyserial is either a version that works with COMxx, or a version that works with /dev/ttyXX, never a version that works with both. We went for COMxx as this is what we figure most Windows developers are more familiar with.)

[f.h-f.s.]

I noticed a change here too, I was using /dev/ttyS3.
Since a esp-idf update, I got errors and now I am using COM4 which works for me.
