But when I checked a little more in detail about Wake signal, it says that to support D3_cold scenarios, the signal should be pulled up to 3.3V_AUX, as shown below: But when I tried to find more information about CLKREQ signal, i dont get much info.. All I get is some timing in...
The application scenario must be used together with the PCIe timing. PCIE_CLKREQ_N The PCIe clock signal is used with the user clock system. In the RC mode, float the signal when it is not used. In the EP mode, the Atlas 200 AI accelerator module outputs data to the PCIe Host. ...
reset. CLKREQ# timing rules are referenced elsewhere in the spec.d) The reset timing diagram and reset variable value tables are modified to reflect (a) and (b),and other changes, such as that “power on” refers to power being valid on the device , not on the system.e) Language ...
Programmable control over connection timing and pin bounce Allows injection of power from an external source Provides active driving of CLKREQ, PERST and WAKE signals Technical Supports PCIe 1.0a, 1.1, 2.0 and 3.0 Supports x1 to x8 device cards ...

We have the gpio for the clkreq assigned to:MX8MP_IOMUXC_I2C4_SCL__PCIE_CLKREQ_BHowever, we cannot see a time when the clock is off. How do we set the clock to off by default?0 件の賞賛 返信 すべてのフォーラムトピック 前のトピック 次のトピック ...
在D3 Hot状态下,当PCIe设备的电源(Vcc)被断开后,则自动从D3 Hot状态进入D3 Cold状态。退出D3 Cold状态可以使用CLKREQ#或PERST#信号或Beacon信号或WAKE#信号。此后,可能还需要一次复位操作,才能使得该Function进入D0活动状态。 配置pcie power status pmcap设置为D3,即可进入D3 hot状态。在D3 Hot的情况下,软件...
CLKREQ# in L1 If the MAC is moving the link to the L1 state and intends to deassert CLKREQ# to stop REFCLK, then the MAC follows the proper sequence to get the link to L1, but instead of finishing by transitioning the PHY to P1, the MAC transition the PHY to P2. Then the MAC ...
