VIOFO MicroSD

[vladkozlov69]

Hi guys,

I just got from Amazon some Viofo Industrial cards - 32G and Viofo 64G.

Viofo Industrial 32G output looks pretty similar to Apacer so I believe it's just a rebranded card:

{
"version": "v0.5.0-2 (aab6b51) arm64",
"date": "2023-10-02T13:14:17.000Z",
"device":"/dev/mmcblk1",
"addTime": "false",
"read_via_cmd56_arg_1":"read successful but signature 0xff 0xff",
"idata.response[]":"0x900 0x00 0x00 0x00",
"flashId": ["0x89","0xa4","0x08","0x32","0xa1","0x00","0x00","0x00","0x00"],
"icVersion": ["0x1f","0xc3"],
"fwVersion": [17,156],
"ceNumber": "0x01",
"spareBlockCount": 13,
"initialBadBlockCount": 13,
"goodBlockRatePercent": 98.71,
"totalEraseCount": 2,
"enduranceRemainLifePercent": 99.94,
"avgEraseCount": 1,
"minEraseCount": 1,
"maxEraseCount": 1,
"powerUpCount": 11,
"abnormalPowerOffCount": 0,
"totalRefreshCount": 0,
"productMarker": ["0x00","0x00","0x00","0x00","0x00","0x00","0x00","0x00"],
"laterBadBlockCount": 0,
"success":true
}

However Viofo Industrial 64G is not so bright... :(

{
"version": "v0.5.0-2 (aab6b51) arm64",
"date": "2023-10-02T13:22:22.000Z",
"device":"/dev/mmcblk1",
"addTime": "false",
"signature":"0x70 0x58",
"manufactureYYMMDD": "2�",
"healthStatusPercentUsed": 78,
"featureRevision": "0x91",
"generationIdentifier": 0,
"productString": "",
"success":true
}

Dangled manufactureYYMMDD attribute suggests that CMD56 output blob format is different so I dumped it:

",

Any ideas what it could be?

according to #8 this could be a "longsys 173" since it has the same signature...
Unfortunately I'm at the moment to busy ("making money for a living") but I'm happy for every pull request ...

[vladkozlov69]

Looks like we already have support for these cards in this opened PR: #12

Then this issue can be closed after merging that PR

@vladkozlov69 ups, so I merged the pull request and fixed the logic... Can you please check if the newly build Development version work with your card?

[vladkozlov69]

@Ognian yes, newly build Development version works with my card just fine! Thanks.
