check if you have all jumpers on the expansion board

[Knoahlr]

@livius Yes I do.

The screen connection stability is improved in every firmware update. Make sure that you are not using any other terminal multiplexers (e.g. tmux or screen inside screen). Open a new terminal window to ensure that there are no such dependencies and use screen /dev/yourdevice 115200.

It might take some time before the REPL appears. If you still don't get it keep the screen connection open and press the reset button on your board.

@sakis Hey, I did this same exact steps a few times and all I was able to see was the output. Also, whenever I was connected to the board using Pymakr and screen at the same time. I could see the exact same output from Pymakr on the screen terminal.

I tried to upgrade the firmware by ftp(ing) the binary file to /flash/sys but now when I reset the board I see a red light and it doesn`t seem to finish booting up.
This what I see on my screen terminal

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0x00
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:QIO, clock div:2
load:0x3fff9010,len:8
load:0x3fff9018,len:312
load:0x40078000,len:2352
load:0x4009f000,len:1196
entry 0x4009f2d8

Booting in safe mode doesn`t help.

@Knoahlr
i also tried before by ftp but it does not work properly
and somwhere in the formu some admin say that it is no longer supported
but i am not sure

to fix problem flash it by updater tool

[robert-hh]

Flashing by uploading appimg.bin to /flash/sys does not work any more since V1.0.0.xxx (or so). You may use the uploader tool, or if you have built you own image, use
make flash

@robert-hh @livius I`m getting an error A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header, whenever I try to use the Upgrader tool. Did any of you experience this problem. Do you think this a problem with my WiPy or the expansion board?

[robert-hh]

Did you connect GP23 and GND & Reset then? That's needed for upgrading via USB/Serial,

[Knoahlr]

@robert-hh Yes I did.

@Knoahlr

as @rskoniec wrote do the following - i have modified two points :

1. Check if you have all jumpers on the expansion board
2. Unconnect (USB) WiPy/LoPy board from PC.
3. Connect wire G23+GND.
4. Connect the board (USB) to PC by shortest usb cable.
5. Upgrade but unselect fast connection in upgrade tool.
6. after sucessfull update unconnect the board (USB) from PC.
7. Remove G23+GND wire.
8. Connect the board (USB) to PC.
9. Check f/w release with os.uname()

you can try also at point 4
when you press upgrade button i upgrader tool or really shortly before
press reset button on the board - this should work
