+====Overview====
 In the new Kindle PW5, Amazon started using different CPU from previous models. Kindle PW5 is using Mediatek MT8113, bundled with 512Mb RAM.\\
 All production devices are locked, which means you cannot use u-boot CLI because on a locked device there is forced execution of fastboot command followed by boot command when you try to access u-boot CLI.\\

 Amazon also removed debug UART connector from the PCB.\\
 On the production devices, the UART Linux shell is disabled.\\

+====eMMC interposer:====
+In order to be able to easily modify, read out, and backup content of the eMMC chip, I created an interposer with the connector on which the board with the eMMC chip is placed.\\
+Pinout was chosen to match the PINE64 eMMC module and [[https://pine64.com/product/usb-adapter-for-emmc-module |reader]]. Unfortunately, the connector used on the PINE64 eMMC module and reader is hard to get, so I used the same pitch, but different dimensions connector. As I check it, it should be possible to place chosen connector to the reader PCB.
+Files are available at GitLab [[https://git.taktpraha.cz/trimen/keib|KEIB]]

+PCBs arrived along with the reballing stencils and balls.
