"my Run-DMD clock has started glitching. It displays a corrupted screen and then returns to clock every 10 seconds instead of showing an animation."
if your clock has started to exhibit these signs, chances are that the SD card has become corrupt and this is what you need to do to fix the issue:
steps to fix corrupted SD cards
- browse to https://rundmdimage.wordpress.com/ and download the latest firmware
NOTE: make sure that you are downloading the firmware for the run-dmd EDGE/white boards, not the pico board. the latest version is B134 (fixed image)
- download HDD rawcopy from here: http://hddguru.com/software/HDD-Raw-Copy-Tool/HDDRawCopy1.10Portable.exe
- run hdd raw copy and select the image file that you download above as the 'source', then click 'ok'
- select the drive letter containing the SD card (don't worry about your computer complaining the SD card needs to be formatted when you insert it into your reader, the way that the information is written, there is no FAT (file allocation table), which is why windows displays the dialog
NOTE: make sure to select the proper drive letter. I take no responsibility for anyone not doing so and formatting a partition of their computer's hdd
- press the 'ok' button and let raw copy do it's job of re-imaging the SD card
- replace the SD card into your run-dmd clock. you may or may not have to hold down button 3 and re-select the proper display type. you will need to adjust the settings that I preset on everyone's clock including (setting the time, adjusting the brightness, enabling all animations)
these adjustments are saved on the SD card which is why you will lose them after re-imaging the SD card
