I decided to update my firmware yesterday and the experience was very problematic, and very frustrating. I first dowloaded the RAR file, which I unzipped with WinZip - see attached jpg showing the extracted contents contained in that RAR file. I then went into upgrade mode without any problem using a paper clip. I then used the update tool to connect to the device. However, when I looked in the folder (icon 1) there was only one subfolder called "platforms" which contained a few hex files related to an OPPO and a PWT device. I couldn't locate the 1.82 hex file. I finally found the 1.82 file in my downloads and when I clicked on it, it loaded as shown in figure 5. I then clicked on the start button (middle icon) and it initiated the erase, program and verify sequence, but it ended up with a message stating that the device failed to verify (instead of stating "Verify Complete" as seen in image 6). I then repeated the process by again clicking on the start button, but it still gave a "Verify Failed" message. I didn't know what to do at that point, so I decided to click on the 3rd icon to start the device - even though device verification failed. The screen then displayed a message stating that the device was disconnected. I presumed that it self-aborted the upgrade process and I expected the device not to start. However, when I started the device (Matrix Sabre-X Pro DAC), it worked and played music and the firmware read 1.82. I didn't truly know if the firmware update was really completed succesfully, so I decided to start the whole update process again from the beginning - even though firmware 1:82 was now apparently loaded into my device. This time the update process worked perfectly, and the device was successfully verified and reset (as shown in images 6 and 7). I then decided to update the XMOS to version 6.6. I started off by unplugging the power to my device and then connecting my laptop to the device with an USB cable. I then entered standby mode by plugging the power cable plug back into the device. When I was in standby mode (not upgrade mode), I was then stuck and I didn't know how to proceed. Instruction 1 stated that I should double-click "Matrix-Audio DFU" in the driver root directory. However, I didn't know how to find the driver root directory. It then stated that I should open the driver installation package to find the upgrade program tool, but I couldn't locate that package or the upgrade program tool. How do I solve this "update XMOS" problem? Jeff.
