== Teardown ==<br />
You can find an excellent teardown of the Amazon Tap at [[https://www.ifixit.com/Teardown/Amazon+Tap+Teardown/61603 ifixit.com]].<br />
<br />
== UART ==<br />
The Amazon Tap features UART pads that provide u-boot boot info but no shell and kernel debug output during boot.<br />
<br />
The UART pads can be found in the photo below.<br />

<br />
== Gaining Bootloader Shell ==<br />
The Amazon Tap implements a secure boot process but a bootloader shell can be obtained by grounding the flash data0 pin while u-boot is reading the kernel into memory. <br />
<br />
To access the bootloader shell.<br />
<br />
# Connect to UART<br />
# Ground resistor next to TP27 silkscreen<br />
# u-boot shell is available when presented with "=>"<br />
<br />
The photo below illustrates the process.<br />
