Ethernet only connect when usb is connected and used by sender

[semos2k]

Hi, i using a board stm32f407vet6 and compiled version of the grblhal activating ethernet, that works correctly when connect first the usb cable and iosender for check boot.

But when not connect the usb cable and power the board from PSU try to connect iosender using the ip not work, testing using ping the ip reponds.

How do you compile and do you have your own board map?

The reason I ask is that this code was added by me to the ST framework to be able to detect if a USB client is connected or not. If it is missing it may explain why.

[semos2k]

my platformio config is

[env:black407ve] board = genericSTM32F407VET6 board_build.ldscript = STM32F407VETX_FLASH.ld build_flags = ${common.build_flags} -Wl,-u,_printf_float -I lwip/src/include -I networking/wiznet -D HSE_VALUE=8000000 -D USB_SERIAL_CDC=1 -D ETHERNET_ENABLE -D BOARD_BLACK_407 -D WIZCHIP=5500 -D TELNET_ENABLE=1 -D WEBSOCKET_ENABLE=1 lib_deps = ${common.lib_deps} eeprom lwip networking lib_extra_dirs = ${common.lib_extra_dirs} upload_protocol = stlink

and my custom map is

/* generic_map.h - driver code for STM32F4xx ARM processors

I have wired up my F446 dev board and that works as it should. Perhaps PlatformIO is using its own framework version without the code modification? Have you checked that?

[semos2k]

No, I have not verified that, how can I verify it?

[terjeio]

By locating the file and checking if it has the added code linked to above. If not replace the file with the one from the repository - there are a few #include files added at the top of it too. In the Web Builder linux server the framework code is located in ~/.platformio/packages/framework-stm32cubef4.

Tip: one way to find out which file the compiler uses is to deliberately add an error in the file.

[semos2k]

I have tried the following: I have removed these two directories, I have compiled and it still does not work.

I have commented USB_SERIAL_CDC support and it works correctly.

[terjeio]

Then check the file in the download. Does it have the changes? It could also be that the (virtual) DTR pin is left in an incorrect state by the OS leading the controller to believe there is a client connected. If so the USB TX buffer will fill up and block all output.

[semos2k]

I do the test by disconnecting the USB connector, and connecting the board to a 5v source directly.

[terjeio]

I do the test by disconnecting the USB connector, and connecting the board to a 5v source directly.

Oops - forgot to test that, seems that I have to figure out how to check for the USB port beeing powered or not.

[terjeio]

Try by changing this function to:

// Welcome message
static void report_init_message (void)
{
    override_counter = wco_counter = 0;

    if(hal.stream.is_connected())
#if COMPATIBILITY_LEVEL == 0
    hal.stream.write_all(ASCII_EOL "GrblHAL " GRBL_VERSION " ['$' or '$HELP' for help]" ASCII_EOL);
#else
    hal.stream.write_all(ASCII_EOL "Grbl " GRBL_VERSION " ['$' for help]" ASCII_EOL);
#endif
}

Note that I am not yet sure if it is the final solution,.

[semos2k]

Yes it worked correctly, thank you

How can you port from VGT6 to VET6? Is it easy by simply modifying the VGT6 FLASH.ld file? Or I have to modify any other file to get it worked?
