The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, computer readable media does not include non-transitory computer readable media (transient media), such as modulated data signals and carrier waves.
The invention provides an OTG optimization method of a mobile terminal, which comprises the following steps:
step S1, determining the corresponding first eye pattern optimal parameter when the mobile terminal is used as the slave device;
for example, when the mobile terminal is connected with a computer, the mobile terminal acts as a slave device;
step S2, determining a second eye diagram optimal parameter corresponding to the mobile terminal as a master device, wherein the mobile terminal is connected with other slave devices through an OTG line when the mobile terminal is used as the master device;
for example, when the mobile terminal is connected to a usb disk and a mouse through an OTG line, the mobile terminal serves as a master device;
for example, the first eye diagram optimal parameter and the second eye diagram optimal parameter are configured as follows:
RG_USB20_PHY_REV6；
RG_USB20_VRT_VREF_SEL；
RG_USB20_TERM_VREF_SEL；

For example, the determined Host and device end eye diagram parameters may be incorporated into the code:
particularly in/drivers/misc/media/usb 20/$ project/usb20_ phy.c
Usb _ phy _ tuning function.
Here, the existing scheme can only simply meet the requirement that the quality of the USB eye diagram signal reaches the standard, and cannot be compatible with the stability of the OTG function. For example, in actual eye diagram debugging, it is found that when the eye diagram parameters of the software are already adjusted to be optimal and the eye diagram test PASS is achieved, the function of the OTG is affected to a certain extent, and a phenomenon of signal instability and connection interruption occurs, which is very poor in user experience. Theoretically, optimization of a hardware level can be firstly carried out to optimize an eye pattern signal and ensure stability of an OTG function, so that the hardware material is expensive, the cost is increased essentially, the eye pattern signal can be adopted on high-end products, but if the eye pattern signal is a low-end product, a large amount of demands are met? It is of course not possible to drive up the overall costs for this small functional stability. If this problem could be solved at the software level, it would not be possible to reduce the cost to a great extent while ensuring the stability of the OTG functionality.
The optimization scheme is simpler, more efficient and more practical on the software level. The OTG optimization scheme based on the eye diagram parameter adjustment can well solve the problem. The stability of the OTG function is ensured while the quality of the USB eye diagram is considered.
The invention provides an OTG optimization scheme based on USB eye diagram parameter adjustment, which can be applied to products of MTK platform supporting OTG function.

The invention provides the method for distinguishing and configuring the eye pattern parameters, and obviously improves the eye pattern signal quality and the OTG functional stability.

Here, in this embodiment, by determining whether the mobile terminal is currently used as a slave device or a master device, and then calling the corresponding first eye diagram optimal parameter or second eye diagram optimal parameter according to the determination result, different requirements for ensuring the USB eye diagram is optimal or ensuring the stability of the OTG function under different scenes can be met.

{(_musb)->is_host＝true；}
#define MUSB_DEV_MODE(_musb)\
{(_musb)->is_host＝false；}
the parameter configuration method comprises the following steps:
u2_vrt_ref＝xx；
u2_term_ref＝xx；
u2_enhance＝xx；
