Could not find or open bootloader

[dividebysandwich]

My RX888MK2 is not recognized on linux mint:

lsusb output:

Bus 001 Device 008: ID 04b4:00f3 Cypress Semiconductor Corp. FX3 micro-controller (DFU mode)

Error message:

$ rx888_stream -f SDDC_FX3.img -r --sample-rate 100000000 -o -
thread 'main' panicked at src/main.rs:214:10:
Could not find or open bootloader
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Here's the syslog when I plug in the device:

kernel: usb 1-9: new high-speed USB device number 9 using xhci_hcd
mtp-probe[3743]: checking bus 1, device 9: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-9"

I also tried downloading the latest SDDC_FX3 from the ExtIO github, no change.

Try with sudo? The application might not have enough permissions to access the device.

[nikulesko]

@rhgndf it works. Thanks a lot.

[dividebysandwich]

Aye that did the trick. For some reason I didn't even think to try this. Thanks!
