XCSoar on Kobo Clara Colour?

[ionelanton]

Hello,
Any intention to support this device?
Thank you!

Its a sweet target. If its built like the other kobos a port shouldnt be too difficult. Anyone un @XCSoar/kobo-team have such a device?

I could test a device but not buy it. I don't see the advantage of the colour, which is very transparent on e-ink colour screens

Hi, I bought a Kobo Clara Color. It does not have a SD card but a eMMC chip.
I tried to install XCSoar on it but without success. The device doesn't boot anymore. Bricked for now.

Have you used such an EMMC adapter for backup?

I believe the thing is soldered to the board.

There is a "manual" reset procedure for this device, https://help.kobo.com/hc/en-us/articles/18332008301719-Manual-reset-Kobo-Clara-Colour-Kobo-Clara-BW

Does anybody have a part number for the eMMC?

[fraktal-sb]

There seems to be a chance to do a backup/restore of the emmc chip

So the best thing would be to identify any connector / test pads corresponding to the JTAG if they exist and if the fuses have not been blown.

Otherwise, as somebody has pointed out the real problem is to 'dd' the saved image back onto the eMMC after it is (inevitably) bricked.

Very interesting topic ! The color is the only missing thing on my Kobo Clara HD + Bluflyvario !!!!

[fraktal-sb]

the eMMC Chip should be this one, next to the test pad S1

[Exadios]

Yes. that is certainly it. Thanks.

So it is a little difficult to tell from the photo. Is U22 mounted on some sort of sub board?
