ref_clk_n接到了MGTREFCLK1_p。这样会影响PC检测pcie设备么？ 目前是大概率检测不到设备。偶尔能够...
Hi everyone! I`m developing PCIe driver for QNX and strugglilng a problem with having access to PCIE controller regisers (i think that some of clock
On a custom board based on the imx8mp we have pcie up and running and can install pcie adapters and use them without issue. However, we are using the internal clock and need it to be off by default and to be able to turn it on when a board is plugged in. Without...
In PCIe mode, you must connect the clock input to the fixedclk port provided by the ALTGX MegaWizard Plug-In Manager. The frequency of this clock input must be 125 MHz. For all other functional modes, connect the clock input to the reconfig_clk port provided by the ALTGX MegaWi...

BIOS中英文对照表 首先先解释下BIOS:BIOS（Basic Input／Output System）即基本输入输出系统，通常是固化在只读存储器（ROM）中，所以又称为ROM－BIOS。它直接对计算机系统中的输入、输出设备进行设备级、硬件级的控制，是连接软件程序和硬件设备之间的枢纽。ROM－BIOS是计算机系统中用来提供最低级、最直接的...

there is an errata that says if the power is on to the PCIe and the clock is not running it will ultimately deteriorate the hardware. So we are examining the possibility of not powering the PCIe if the module is not present (which will have the same effect as not h...
Hi, I using PCIe gen 4 (16 lanes) (512bit/500MHz clk , payload size:256B) CORE, in Agilex device: AGFB014R24A2E2VR0. Tests performed found that the
