Tried 6 different SD cards: Class 10, Class 10 U1, Class 10 U3 with 4GB, 16GB, 32GB size, Kingston and Sandisk brands.\r\nThe issue is reproduced on all these cards and they all work with the same F722-STD running Betaflight 3.5.2.\r\n\r\n## Steps to Reproduce\r\n1. Perform defaults on F722-STD running INAV 2.0, restore the provided diff and save.\r\n2. On the Blackbox tab, the message \"Filesystem Starting...\" is shown and the card does not start at all.\r\n2. Change ESC protocol to anything else except ONESHOT125 or ONESHOT42, save and reboot.\r\n3. On the Blackbox tab, the card is shown to be ready to accept Blackbox records.\r\n\r\n## Expected behavior\r\nThe SD Card Blackbox system should work with ONESHOT125 or ONESHOT42 ESC protocol with HEX X mixer profile.\r\n\r\n## Additional context\r\nCLI dump diff for INAV 2.0 F722-STD\r\n[F722-STD_INAV200_ONESHOT125.txt](https://github.com/iNavFlight/inav/files/2506061/F722-STD_INAV200_ONESHOT125.txt)\r\n\r\n\r\n---\r\n<!-- PLEASE FILL THIS OUT -->\r\n<!-- Use CLI 'version' command to get version string -->\r\n\r\n- FC Board name and vendor: INAV/MATEKF722\r\n- INAV version string: 2.0.0 Aug 20 2018 / 19:21:31 (dbdd1656a)\r\n"},"comment":{"url":"https://api.github.com/repos/iNavFlight/inav/issues/comments/432261254","html_url":"https://github.com/iNavFlight/inav/issues/3945#issuecomment-432261254","issue_url":"https://api.github.com/repos/iNavFlight/inav/issues/3945","id":432261254,"node_id":"MDEyOklzc3VlQ29tbWVudDQzMjI2MTI1NA==","user":{"login":"Frontier314","id":4806480,"node_id":"MDQ6VXNlcjQ4MDY0ODA=","avatar_url":"https://avatars0.githubusercontent.com/u/4806480?v=4","gravatar_id":"","url":"https://api.github.com/users/Frontier314","html_url":"https://github.com/Frontier314","followers_url":"https://api.github.com/users/Frontier314/followers","following_url":"https://api.github.com/users/Frontier314/following{/other_user}","gists_url":"https://api.github.com/users/Frontier314/gists{/gist_id}","starred_url":"https://api.github.com/users/Frontier314/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Frontier314/subscriptions","organizations_url":"https://api.github.com/users/Frontier314/orgs","repos_url":"https://api.github.com/users/Frontier314/repos","events_url":"https://api.github.com/users/Frontier314/events{/privacy}","received_events_url":"https://api.github.com/users/Frontier314/received_events","type":"User","site_admin":false},"created_at":"2018-10-23T14:06:32Z","updated_at":"2018-10-23T14:06:32Z","author_association":"NONE","body":"@teckel12: Yes, I have tried Multishot/Standard/Brushed with the same setup (without my ESCs connected) and the SD card is recognized. The problem however is not the OneShot125/OneShot42 protocol but the combination of that with Hex X6 mixer; if I keep the same configuration as posted above but change the mixer to Quad X, the SD card(s) are recognized.\r\n\r\nMy ESCs are Flycolor Raptor 30A running BLHeli 14.6 (or 14.9, I do not remember exactly which of the two) and I am pretty sure they do not support Multishot protocol. Unfortunately, I cannot easily change the ESCs and - frankly - I do not want to as most of the new ESCs of that size run BLHeli32 and only support DSHOT which I think INAV does not currently support. The same set-up works with Betaflight 3.5.2 but I do not want to use Betaflight; I want INAV for the GPS functionality :)\r\n\r\nThank you very much for your time and advice."}}
