Hello, I am currently experiencing difficulties with the SD card backup and restore feature for a Micro820. While I can successfully modify the default directories using [UPD], I am encountering issues with actually restoring projects using the BKD and RSD commands. My goal is to utilize a single 32GB Sandisk Ultra SDHC card, formatted to fat16 with a 2GB volume, to automatically restore a project upon power-up. However, I am facing obstacles in the restoration process. Additionally, I have noticed that the SD card indicator light turns off after the boot-up sequence, requiring me to re-insert the card for it to be recognized by the controller, despite having only [END] in the ConfigMeFirst.txt file. Any assistance with this matter would be greatly appreciated. Thank you for your help. SD Card Details: - 32GB Sandisk Ultra (Class 10) SDHC - Currently formatted to fat16 with a 2GB volume (remainder unallocated) - Root directory contents: - FIVE - SIX - ConfigMeFirst.txt lines: - [CF] - [RSD=SIX] - [END] Project Settings
The firmware associated with micro820's SD card functionalities has encountered previous issues that may or may not have been addressed. Have you attempted to reach out to AB directly to report the issue? It is possible that the size of your SD card is too large; however, reformatting and allocating 2gb of space could potentially solve this issue. While I have successfully stored error logs on SD cards, I do not have the same level of success when it comes to running commands or uploading code.
It looks like you're experiencing multifaceted issues here with your Micro820 and your 32GB Sandisk Ultra. Starting with the SD card, could you consider reformatting it to FAT32 instead of FAT16? The Micro820 shows more compatibility with FAT32 filesystem. Additionally, ensure the 2GB volume you've partitioned is large enough to house your project backup. If your project settings are larger, it might not restore correctly. Your post-boot issue could possibly be due to the [RSD=SIX] command in your ConfigMeFirst.txt file. Just to clarify, have you verified that 'SIX' is the correct directory for your desired project? The off light indicator might be a result of the controller not finding the requested file or directory. Confirm this and if need be, modify the directory or the [RSD] command in your ConfigMeFirst.txt file. Let's start with these suggestions and see how it goes from there.
Hey there, it seems you're stuck between a rock and a hard place with this SD card restoration issue! One thing to keep in mind with SD cards, especially the SanDisk Ultra ones, is that they are sometimes finicky about the format they are in. I know you've formatted it into Fat16, but you may want to try Fat32 to see if that makes a difference. Also, double-check the project backup file, ensure it's not corrupt which can happen with backups in the root directory. The light going off might be an indication of a communication issue between the controller and the SD card. Try to update the card reader's driver if possible, as they can sometimes be incompatible with higher storage cards. Hope this helps!
It sounds like you've set up everything correctly according to your specifications. But for the issue with the SD card not being recognized after boot-up, it might be related to the controller having difficulties dealing with the larger capacity card. Try using a smaller capacity SD card, like an 8GB or 16GB, and see if the problem persists. If the problem still occurs, it may be a controller issue. Also, ensure you are using the most up-to-date firmware. Although you correctly formatted it to FAT16, sometimes high capacity SD cards may present unforeseen issues. Additionally, make sure that your SDHC card meets the requirements of the controller for minimum and maximum speed.
In troubleshooting your problem with the SD card backup on your Micro820, I would first suggest you recheck the formatting of the card. Although you've formatted it to fat16, it may be worth re-formatting the SD to FAT32, since some users have reported that it works better, especially for larger capacity cards like yours. The issue of the indicator light going out and the card needing to be reinserted could be due to the card not being properly ejected or some intermittent connection problems. Try using a different SD card slot or a different SD card itself to isolate the problem. For the restoration process, if the location of the project is in a subfolder, you need to include the path in the RSD line i.e. [RSD=FIVE/SIX] if SIX is within FIVE. I could be wrong, but it might be worth a shot. Let me know if your situation improves!
It sounds like you're facing quite a complicated issue with your Micro820 setup! Since the SD card indicator light turns off after boot-up, it could indicate a power management issue with the card or compatibility problems with the controller. First, make sure your firmware is up to date, as newer versions might fix bugs with SD card recognition. Also, consider trying a different SD card if possible, as sometimes certain models have unexpected compatibility issues. Lastly, when setting up your ConfigMeFirst.txt, double-check that the commands are formatted correctly and experiment with removing any extra lines temporarily to see if that helps with the restoration process. Good luck, and I hope you're able to get it all sorted!
It sounds like you're encountering a couple of tricky issues there! For the restoration problem, have you confirmed that the path in your ConfigMeFirst.txt is accurately pointing to the project folders? Sometimes even a small typo can throw it off. As for the SD card not being recognized until you re-insert it, that could indicate a power or initialization issue with the card reader on the Micro820. You might want to check if the card is seated properly or try it with a different card to rule out a hardware problem. Also, if you haven't already, consider using the full capacity of your SD card by formatting it to FAT32, as that can sometimes help with compatibility and performance issues. Good luck!
