Hello everyone, I work with Matteo on CUInspace and am currently trying to get Nuttx to recognize two partitions on a SD card. Currently I'm a little confused on how to use / implement parse_block_partition. I did find a previous thread on a similar subject ( https://lists.apache.org/thread/q19rdvst6k687s4v045q362j68r2so1t <(https://lists.apache.org/thread/q19rdvst6k687s4v045q362j68r2so1t>), but I am a bit lost trying to follow the code, specifically on where would be the best place to call parse_block_partition. If anyone has any experience with mounting an SD card with multiple partitions any help would be appreciated! Thanks, Tony
