For the iMX6SDL, the Linux PCIe driver sets the DEVICE_TYPE in GPR12 to 0x4 for RC mode: // set device type to RC (PCI_EXP_TYPE_ROOT_PORT=4 is from pcie_regs.h) imx_pcie_clrset(iomuxc_gpr12_device_type, PCI_EXP_TYPE_ROOT_PORT << 12, IOMUXC_GPR12 ); This ...
Because SSD SoCs interface with both non-volatile memory express (NVMe) or Flash memory as well as root complex processors, the bandwidth requirement is quite high. But SSDs are limited by the bandwidth in the SSD socket, which is gated by the PCIe data rate. That means that getting ...
One unique feature? "The fight training sequence is automatically managed by embedded firmware —there’s no involvement from the user to train the either the PCIe5* or the DDR5*,” he adds. “We’re also bringing in new capabilities for RASDES for...
What did the host cpu (Intel-Core-i-Serie) do when a PCIe read completion abort occur (no advanced error reporting is enabled)? In my imagination: If the host cpu initiates a pci-memory-space-read and if the response was a read completion abort, the ro...
1. How to start to make the PC as Root complex and the DSP as endpoint. I found example in C:\ti\pdk_C6657_1_1_1_4\packages\ti\drv\pcie\example\sample , but both RC and EP are implemented on DSP device..if it is possible i want to develop RC code inside the Driver ...

An SBC or single board computer, appears as a complete computer board including standard peripheral connectors such as power input, RJ45 Ethernet jacks, USB ports, Mini-PCIe slots and GPIO headers. An SBC is an embedded system that contains all the brains (CPU, DRAM, Flash), supporting extern...
To satisfy the world’s insatiable demand for data anytime and anywhere, storage devices are rapidly evolving and competition in the HDD and SSD storage arenas is getting fierce. At the heart of SSDs are complex controller SoCs that manage and monitor the integrity of incoming and outgoing ...
Direct hardware access through bare metal environments eliminates virtualization overhead by providing complete control over GPU hardware, CUDA drivers, and system resources. This enables full PCIe bandwidth utilization without contention, custom CUDA driver configurations, direct memory access (DMA) for opt...
Connecting of the other 3-lanes (as optional) provides a 4-lane PCIe interface to the root-complex, however this requires some on-board options to disable the optional channels since there is no on-chip capabilities to completely disable the optional lanes. ...
