Upload firmware through USB

[flygja]

Hi, is there a way to upload firmware through USB? I see some guides on other 32-bit boards saying that the controller's SD card slot will appear as SD card device on Windows 10 - copy and paste firmware then reset the printer. But doesn't seem to work for SGEN L? I see "Marlin SDCard 01 USB Device" in device manager but its not enumerated on windows explorer. I see the disk in diskmgmt.msc but it shows no media even when I have a microSD card plugged in.

Thanks.

Hi! You can copy the firmware to the TF card on the motherboard through the computer. The computer can directly access the TF card on the motherboard.

Hi Flygja I'm facing the same problem with the TMC 2130 drivers on the SGEN_L, is there any way you could share your configuration file with me? Much appreciated (sorry this seems to be the only way I can contact you)

Hi gukaixu, I haven't been able to get it to work. Even with microSD card plugged into the motherboard, there is no folder that appears in windows explorer for the printer.

Thanks for taking the time to reply flygja. I initially want to test without SPI mode, so just in "normal mode" with the 3 jumpers configured. Do you think it is still needed to define the TMC_USE_SW_SPI? I did try this but unfortunately no success for me...

/**

• Software option for SPI driven drivers (TMC2130, TMC2160, TMC2660, TMC5130 and TMC5160).
• The default SW SPI pins are defined the respective pins files,
• but you can override or define them here. */

  define TMC_USE_SW_SPI

  define TMC_SW_MOSI -1

  define TMC_SW_MISO -1

  define TMC_SW_SCK -1`

Oh you were asking about the previous issue I posted. I'm not sure if need to define TMC_USE_SW_SPI if not using SPI mode, I didn't try it in standalone mode. Sorry.
