Error When Writing to SD Card on cRIO
Solved!
Hello,
I am trying to use a SD card to store information acquired by my cRIO-9040.
The SD card in question is an ADATA 16GB UHS-1 microSDHC card with an adapter for SD card size, its default file system is FAT32.
When connecting to the cRIO, I can access the card's contents via the remote file browser (the card's directory is V:) and can download files. However, when attempting to write new data to it, I get error messages.
When trying to create a new folder via remote browser, I get a "403 Forbidden" error.
When trying to create a new text file, from the same method, I get a "500 Internal Server" error.
Finally, when running a VI that creates a new file and stores data to it (I verified that this VI works for USB flash drives), I get an error of code 6.
According to its specifications, the cRIO-9040 supports SDHC cards.
This page says that FAT32 filesystem is both support and recommended: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P7iaSAC&l=en-GB
This page also says that 16GB cards are supported (although it specifies SD, not microSD cards): https://www.ni.com/en-gb/support/documentation/supplemental/18/compactrio-industrial-sd-card-accesso...
Does anyone know how to fix this problem? Is it an issue with the card, or with the cRIO?
Greetings,
I eventually solved it, but completely forget to post it.
Essentially, if you are using a micro SD card with adapter, as I was, you have to turn off the switch that puts the card in read-only mode.
Not sure if this will solve your problem. It seems compactRIO does not work with 64GB cards.
