[Q] SD Card will not boot.

[rorius]

Hi, long time lurker, but I finally had to create an account because I'm flat out stuck.

I'm trying to fix Nook Color for a neighbour, the screen was cracked so she bought a new and I installed it. It works... "kind of." The touchscreen doesn't work. So, I figured why not try to install CM7.2 on it, maybe it has a driver the emmc (I think that what you call it) doesn't have since the screen might be newer. I don't know, it's the only thing I can think of, I tripled checked all the connections from the screen to the board.

Now the NC never boots of the uSD. The uSD looks great, image applied and packages ready, but after the boot up I get the Nook Setup screen (image attached) and then when I look on the uSD there are additional files (image attached) the NC put on there.

I've create the bootable uSD with the follwing images.

• TWRP_2.3.0.2-encore-sdimg.img
• 1gb_clockwork-3.2.0.1-eyeballer.img
• 8gb_clockwork-3.0.1.0.img

All three images were tried with both the following commands and on 2 different 8gigs uSD's (PNY/SanDisk), one USB uSD reader and one those uSD in a SD card adapters.

• sudo dd if=/Users/x/Downloads/TWRP_2.3.0.2-encore-sdimg.img of=/dev/disk2 bs=1m
• sudo dd if=/Users/x/Downloads/TWRP_2.3.0.2-encore-sdimg.img of=/dev/disk2

I'm about to give up, but thought someone here might have another suggestion I can try.

Thanks!

The screen has two components, the lcd display and the the touch matrix (digitizer). Did you replace both?

And sometimes getting an SD to boot can be difficult. See my NC Tips thread linked in my signature and read item A9. Are you sure you are dding to the correct disk partition? Needs to be the whole device.

Hey leapinlar, I honestly don't know. It was one assembled screen unit, I've attached an image, the one on the left is the original and the the right side is the replacement, can you tell from the image if the digitizer is included? Thanks!

I've not actually take one apart, so I don't know. You might search for a Nook Color tear down on the web. Seems to me I saw one years ago.

That is a Nook Tablet, not a Nook Color. That start-up screen will say "Thank you for choosing NOOK Tablet™. We are sure you will love it! Please take a moment to set up your device." for the tablet, and "Thank you for choosing NOOK Color™. We are sure you will love it! Please take a moment to set up your device." for the Nook Color. Look at the text on the back of device under the speaker, and you will see model number BNTV250 or BNTV250a for the tablet, and BNRV200 or BNRV200a for the Nook Color.

Thanks GMPOWER, you are correct, it is a NT and the screen is suppose to be for a NT too. I've found this out from the neighbor after your post. I've attached images of both and it seems that they are the same? I keep hearing about to check if it has a digitizer, but I don't know how or where to look for this...

You don't show the front of it, but usually on devices the digitizer is between the glass and the lcd panel. Is it one unit with glass and lcd panel?

Yes, both are one unit.

Jump back to the first post. You say it's kind of working. Even though you have installed the completely wrong CWM and ROM for It?

Did the neighbor run CM10 prior to the screen breaking. In that case the multi-touch firmware may have been installed. Make a bootable CM10 card for the correct devices and try again.

Here is a link to a ready-made sd image for the Tablet. PLEASE NOTE THAT THIS IS NOT FOR THE COLOR! http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/

If you are looking at the front of the screen with the “n” button facing down, the ribbon on the right of the screen is the touch screen digitizer. All Nook Tablets came with the FocalTech FTx06 digitizer, and most Nook Color’s came with the Cypress Semiconductor TMA340 digitizer. Starting with the Nook Color 1.3 firmware, driver support for the FocalTech FTx06 was implemented. A number of blue dot Nook Color’s come with the same FocalTech digitizer as the Nook Tablet. A Cypress Semiconductor touch screen driver is included in the Nook Tablet kernel source code, but I don’t believe fully implemented.

I attached the following pics of the Nook Color, and Nook Tablet digitizer semiconductors chip. The Nook Color digitizer is the one with 8CTMA340-48LQI-01 CYP644895 PHI written on the chip, and the Nook Tablet digitizer is the one with FT5406EE8 ERE344D K01 written on the chip. If the digitizer in your neighbor’s device is the Cypress chip, it will most likely never work without some work to implement the correct driver into the kernel. She will need to try to return digitizer that she purchased, and get the correct one. Tell her to ask the seller next time before she purchases to verify that it has the correct FocalTech digitizer. If the digitizer is the correct FocalTech digitizer, and all connections are correct, then she should return the faulty one, and get another one that works.

GMPOWER, I think you got it! The one the neighbor was sent it a CYP512226. Last question, if she was to exchange it can it be for any FTxxxxxxx or is there a specific series to ask for? Thanks for the help.

She will need to get the Nook digitizer using the FT5406EE8 chip. The driver in the source code is specifically written for that one.

The FT5x06 series of digitizers consists of three different chips, FT5206GE1, FT5306DE4, and FT5406EE8. The FT5206GE1 chip is designed for touch panels sized 2.8” – 3.8”, FT5306DE4 is designed for touch panels sized 4.3” – 7”, and the FT5406EE8 is designed for touch panels sized 7” – 8.9”.
