USB card reader prevents OPiPC booting (ver. 2016-08-06) #72

At least these devices (card readers) prevents OPiPC booting

When power is connected no LED is going to light. No HDMI output.

At least first device was used with 2016-05-10 and this install was later manualy updated to version to 2016-06-02. It worked without this issue.

Card reader must be without card - with inserted card OPiPC boots.

What about an older image?

vlna commented 8 years ago

Version 2016-05-10 worked for me, then I updated to version 2016-06-02. I used update file (not fresh install) and it still worked.

Maybe U-Boot USB has something to do with this issue... What if you update, actually downgrade, to last version which works. Then you untar 2016-08-06 update file and copy over KERNEL and SYSTEM files. Also please delete script.bin and copy over opipc.fex and rename it to script.bin. That way you will be left with old U-Boot but newer system.

Fresh OpenELEC-H3.arm-7.0-devel-20160602225514-r22840-g4575bc2-opipc.img boots with empty card reader connected.

I would like to follow test you described but it is not clear for me what to do, where start. Could you explain it with more details.

  1. prepare fresh OpenELEC-H3.arm-7.0-devel-20160602225514-r22840-g4575bc2-opipc.img image.
  2. download update file to 2016/08/06
  3. extract update file (untar)
  4. insert sd card to pc and open FAT partition (512 MB in size)
  5. replace KERNEL and SYSTEM files from extracted update file (target/ subfolder)
  6. delete script.bin
  7. copy over opipc.fex from 3dparty/bootloader subfolder from update file
  8. rename opipc.fex to script.bin

you should have newer files on your sd card FAT partition, but same U-Boot

OPiPC with empty USB card reader boots with old U-Boot and new KERNEL, SYSTEM and script.bin.

ok, then I will disable USB in U-Boot and give you update file to test. I would do it anyway as it will speed up booting.

Can you try this update? Link is valid for 14 days. https://transfer.sh/ebKy3/openelec-h3.arm-7.0-devel-20160817211715-r22886-g5828aec.tar

I disabled USB and fix U-Boot update procedure.

vlna commented 8 years ago

I updated ver. 2016-08-06 with provided update file and now OPiPC boots even with card reader connected. I think green LED now turns on faster after connecting power than in previous versions.

Both was intendent. Fixed in 72d778d145aff54deef3f899f6ce07bd2df71006.
