Zynq BootROM Secrets: UART loader

Recently I acquired (md5: ADF639AFE9855EE86C8FAAD216C970D9) the Zynq bootrom, and during the reversing process uncovered some interesting secrets, one of which is an as-of-yet undocumented UART loader. As documented the Zynq bootrom will load from NOR/NAND/SPI flashes, eMMC/SDIO-based storage (unfortunately) not USB, or anything else more complex.

Not sure why Xilinx didn't document this. In my brief testing it is super unreliable if you just spit everything at once - they reset the RX/TX paths during the process, so timing is critical, but that might be the janky meter-long ftdi cable. You can change the baudrate during the process, but I was too lazy to do the math.

Here's the disassembly that made me look twice (that, and checks for the MIO boot_mode[2:0] that weren't specified in the docs :)):

Raspberry Piにroot-roを適用する手順メモ (2018/3/26)

今回使用したイメージはRaspian Lite 2018-03-13版。 まずEtcherを使ってイメージをmicroSDへ書き込む。

イメージ書き込み後、PCからmicroSDにあるconfig.txtを編集する。

TDP and turbo parameter modification with MSR on non-overclockable CPU

Disclaimer

• MSR modification may void your CPU's (or system board's) warranty. Proceed with care. I'm not responsible for any destruction caused by this article.
• MSR address (greatly) differs from CPU to CPU. Check your own CPU's MSR address using Intel's documentation.
• Only tested on Intel i7-8550U (Kaby Lake R).
• This article is translation of this article. If you can understand Korean, I recommend reading that article, not this.
