Maybe use this for flash programming?

Or this:

Or use SiLab's "Simplicity Studio".

Or use their Windows command line tool in Wine.

There is a command line flash tool in Simplicity Studio. Secret revealed by SiLabs support:

If you have installed Simplicity Studio on the Linux machine then the 8051 command line tool for flashing images is also installed. The file will be in the [SIMPLICITY_STUDIO_INSTALLATION]/developer/adapter_packs/c8051. The name of the tool is flash8051 and typing flash8051 -? will give a usage summary.

My 8051 board is putting up resistance. I haven't been able to program it from Simplicity Studio, or the flash8051 command line tool.

The tools says

OSX firmware update in progress.Bootload Run Command failure: status:00, FWresponse:00.
Firmware execution error: status:00.
Incorrect Firmware version download!Communication could not be established with the specified adapter.
Please confirm the current adapter selection and cable connection.flash8051 [ERROR: Bootloader returned failure response.]

And I see this in the system log when I attach the board through USB:

hid-generic 0003:10C4:8253.0004: usb_submit_urb(ctrl) failed: -1
hid-generic 0003:10C4:8253.0004: timeout initializing reports

Hi,

I had the same issue and found that the following line to the GRUB_CMDLINE_LINUX_DEFAULT option fixed the issue:

usbhid.quirks=0x10c4:0x8253:0x20000000

This removed the usb_submit_urb(ctrl) failed: -1 issue and the Linux version of flash8051 now returns the correct reply.

Wow, thank you very much for this hint!
