Hello, I am facing the same issue as the one referenced below. I have taken the necessary steps to ensure that the driver is not causing issues. I have also tried making my baud rate 115200. I am on Ubuntu 22.04. Any tips on how to get around this?

All, just got my new SparkFun Edge, trying to build and flash test program, build is OK, but flashing failed.

I'm using Ubuntu 19.10. I've followed this link https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all#linux

So CH341 driver issue is not a problem, after plugin the USB serial to my PC, dmesg shows:

[66495.174916] usb 1-1.2: new full-speed USB device number 23 using ehci-pci [66495.284880] usb 1-1.2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.64 [66495.284885] usb 1-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [66495.284888] usb 1-1.2: Product: USB Serial [66495.285859] ch34x 1-1.2:1.0: ch34x converter detected [66495.287652] usb 1-1.2: ch34x converter now attached to ttyUSB3

Following this step, https://learn.sparkfun.com/tutorials/using-sparkfun-edge-board-with-ambiq-apollo3-sdk/, I tried to flash Code to Board
