Issue with TXE

Issue with TXE

<p>Hi ,</p>

<p>I don't know if I'm at the right forum if no I'm sorry.</p>

<p>I develop a product with Apollo Lake SoC, the power up sequence is going OK until the moment the SoC suppose to toggle the PLTRST_N.</p>

<p>One of the step that happen in the power up sequence is reading from the SPI flash CSE (the same like TXE).</p>

<p>The SoC is reading the descriptors from the SPI Flash and than stop.</p>

<p>Do you know if it something that can cause the TXE?</p>

<p>I saw in the INTEL Flash Image Tool a&nbsp; "OEM public key hash" does the SoC is checking it in the descriptor or only after the BIOS is running?</p>

<p>I have a key that I burn to the BIOS binary, how could I know that I am using the right one?</p>

<p>Thank you.</p>
