XO-1 external SD card slot detection fails in tests, works with file access

[earias]

With SD either present or absent, the external SD card slot test fails:

ok test ext:0
No card in SD slot
ok 

However filesystem access works fine.

The test should not fail if filesystem access is possible.

Thank you for your problem report.

Fixed by svn 2975, a missing external SD card will no longer halt the test.

Please test with http://dev.laptop.org/~quozl/q2f10jb.rom

Related ticket: #11612.

I have tested http://dev.laptop.org/~quozl/q2f10jb.rom.

Don't show error, but dont detect external sd card.

[Quozl]

Yes, certain SD cards are not detectable, in either Q2E45 or Q2F10. I have one here. Other SD cards work fine.

Please use the show-cid command in Q2F10 to obtain the manufacturing identity of the SD card, like this:

ok select ext:0
ok show-cid

This should print one line of text, please tell me what it says.

[earias]

Correctly. The system detects external sd card only if you have disabled-security.

Can you generate q2f11 with #11612 solution?

[Quozl]

Q2F11 released.

Replying to Quozl:

Please use the show-cid command in Q2F10 to obtain the manufacturing identity of the SD card, like this: {{{ ok select ext:0 ok show-cid }}} This should print one line of text, please tell me what it says.

There are thousands of USB and SD cards in use around the world. OFW should be able to detect the presence of them all; the customer should not have to identify each card, thousands, in use in their deployment.

Test using q2e41:

-Insert SD Card -run test /sd -No result displayed - Assume Pass

-Remove SD Card -run test /sd -"No Card Inserted Displayed" displayed

-Insert SD Card -Boot XO run automatic full tests -Test /pci/sd@c,1 -No result displayed - Assume Pass

Switch to q2f11:

-Insert (SAME) SD Card -Launch Graphic Test Menu using left rocker -Switch to SD -testing ext:0 -No Card Inserted

-Remove SD Card -Launch Graphic Test Menu using left rocker -Switch to SD -testing ext:0 -No Card Inserted Displayed

-Insert SD Card -Boot XO run automatic full tests -testing ext:0 Displayed -No Card Inserted

The perception from the team at Ceibal is that when the Graphical test menu was back ported to the XO -1 the SD port mapping was not changed correctly.

svn 2990 seems to improve the situation. It fixes a problem that is specific to the SDHCI hardware implementation on XO-1, in which it is necessary to turn on some enable bits before the card insertion bits become visible.

[Quozl]

reviewed and tested svn 2990. reuben, please test build http://dev.laptop.org/~quozl/q2f11jc.rom

[Quozl]

Any update?

[reuben]

Waiting for testing.

[reuben]

Tested okay by earias

[Quozl]

Thanks, will be in next release.

Adjusted ticket summary and description to match what has been learned.

[Quozl]

Is in Q2F12.
