usb_interrupt_read in read_usb returned -110 : Connection timed out

[kaklik]

I successfully compiled the ec2tools and tried to program the bootloader into the Si1060. Unfortunately, I am getting the following error.

$ ./ec2writeflash --port=USB --mode=c2 --eraseall 
/home/kaklik/Downloads/ec2-new/src/ec2tools/.libs/ec2writeflash:ec2drv.c:2123: 
usb_interrupt_read in read_usb returned -110 : Connection timed out
Exiting now
/home/kaklik/Downloads/ec2-new/src/ec2tools/.libs/ec2writeflash:ec2drv.c:2123: 
usb_interrupt_read in read_usb returned -110 : Connection timed out

The firmware revision in the adapter is 0x28. The Power and Run/Stop LEDs light up during the command execution and even after the timeout.

A different adapter with revision 0x02, only briefly lights up the Power LED and gives the following output:

 $ ./ec2writeflash --port=USB --mode=c2 --eraseall 
Incompatible EC3 debugger firmware version,
Versions between 0x07 and 0x28 inclusive are recommended
Newer versions may also be tried and will just output a warning that they are untested
Exiting now
Disconnect done

This looks to be a more recent device model that was never configured in the tool. Please refer to https://github.com/paragonRobotics/ec2-new/blob/master/src/ec2drv/device_table.csv and you'll need to try making a new row for the Si1060 (maybe copy and edit from one of the other Si10x0 rows?) and rebuild the library to see if you can get it working. Unfortunately it can take a bit of time on some of the models due to weird unknown techniques SiLabs uses on them. If you're luck though, editing a close sibling model and correcting the memory size/etc will be enough to get it working.

The Deviceid and Derivativeid will need to be figured out based on the USB output from the device. You should use the verbose/debug output option to try the ec2testany script to confirm what numbers your Si1060 chip responds with at the beginning.

I tested this with my recompiled fork (https://github.com/kaklik/ec2-new) and added the Si1060 entry to device_table.csv as in this commit: ThunderFly-aerospace/ec2@d840428 — but ec2tools still behaves the same.

Interestingly, the original ThunderFly fork (where this change was made years ago) also no longer works now, in the same way, though I was used to it. This suggests that the issue might be caused by an external change (e.g., in libusb or kernel behavior), rather than the missing device entry.

It might be worth testing the current code with a previously supported device to confirm whether this is a broader regression. But I do not have any other device than Si1060.
