Embodiment 1

[0027] The configuration method of COMe module high-speed serial port based on PowerPC T2080 includes the following steps:

[0028] Step 1: Start up and run the PBL program to obtain the RCW value from the external memory;

[0029] Step 2: Write the RCW value into the RCW register of the T2080 processor;

[0030] Step 3: Initialize the SerDes to complete the configuration of the high-speed serial port.

[0031] RCW value writing specifically includes: RCW value 1 configures 1 PCIE x4, 1 PCIEx1, 2 SATA interfaces, RCW value 2 configures 2 PCIE x4 interfaces, RCW value 3 configures 2 SRIOx4 interfaces.

[0032] Software configuration The high-speed serial port is configured through RCW, and the RCW register of the T2080 processor with multiple interfaces is added to change the type of high-speed serial port by software configuration. Some modules have fewer interfaces and fixed interface types, resulting in poor flexibility of use. This has achieved the effect of increasing th...

Embodiment 2

[0034] COMe module based on PowerPC T2080, including T2080 processor, PCIE switch, ASD controller and COMe connector; the T2080 processor is connected to the PCIE switch through the PCIE bus and then connected to the COMe connector, and the T2080 processor is also connected to the COMe connector through the ASD controller The low-speed interface on the T2080 processor is also connected to the high-speed serial port on the COMe connector through the PCIE bus. The T2080 processor includes an RCW register for realizing software configuration of the high-speed serial port.

Abstract

The invention discloses a COMe module high-speed serial port configuration method based on a PowerPC T2080 and a COMe module and relates to the field of COMe processor modules. The method comprises the steps that 1, startup is performed to run a PBL program, and an RCW value is obtained from an external memory; 2, the RCW value is written into an RCW register of a T2080 processor; and 3, SerDes isinitialized to complete configuration of a high-speed serial port. The module comprises the T2080 processor, a PCIE switch, an ASD controller and a COMe connector, wherein the T2080 processor is connected with the COMe connector after being connected with the PCIE switch through a PCIE bus, the T2080 processor is also connected with a low-speed interface on the COMe connector through the ASD controller, the T2080 processor is also connected with the high-speed serial port on the COMe connector through a PCIE bus, and the T2080 processor comprises the RCW register used for realizing software configuration of the high-speed serial port. Through the method and the module, the problem that an existing module is poor in use flexibility because a small number of interfaces are arranged and theinterface type is fixed is solved, and the effects of expanding interfaces, simplifying hardware design and improving the use flexibility and reliability of the module are achieved.

Description

technical field [0001] The invention relates to the field of COMe processor modules, in particular to a PowerPC T2080-based COMe module high-speed serial port configuration method and the COMe module. Background technique [0002] PowerPC T2080: NXP's high-performance processor; COMe: COM Express is a computer-on-module standard defined by the International Industrial Electrical Association (PICMG); TYPE7: a new interface standard in the COMe specification. [0003] SerDes is the abbreviation of Serializer / Deserializer, which is a time-division multiplexing TDM, point-to-point P2P serial communication technology; that is, at the sending end, multiple low-speed parallel signals are converted into high-speed serial signals, and then transmitted through the transmission medium At the receiving end, the high-speed serial signal is reconverted into a low-speed parallel signal; this point-to-point serial communication technology makes full use of the channel capacity of the transm...
