Bootloader writes with a brush dipped in Chinese ink step, and user can realize that by inserting SD card Bootloader updates operation, with it is simple to operate, can
By the good advantage of property；After the test automobile installs the automobile-used BootLoader commissioning devices, primary processor is simplified
BootLoader updates step, is easy to the test and debugging of vehicle.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is the theory diagram of automobile-used BootLoader commissioning devices of the present utility model.
Fig. 2 is the theory diagram of this controller；
Fig. 3 is the connection block diagram of CAN and controller.
Specific embodiment
This utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Basic structure of the present utility model is only illustrated in a schematic way, therefore which only shows the composition relevant with this utility model.
In embedded OS, BootLoader was run before operating system nucleus operation, can be initialized
Hardware device, memory headroom mapping graph is set up, so as to take the hardware environment of system to a proper states, so as to for final
Call operation system kernel gets out correct environment.
Embodiment 1
As shown in figure 1, this utility model provides a kind of automobile-used BootLoader commissioning devices, including：With automobile instrument
The controller that middle processor is connected, the controller include：The SD card that data are write with a brush dipped in Chinese ink for reading Bootloader in SD card connects
Mouthful, be connected with the SD card interface be suitable to according to Bootloader write with a brush dipped in Chinese ink data renewal Bootloader primary processor.
When in use, by SD card interface grafting SD card, the primary processor is by reading what is stored in SD card
Bootloader writes with a brush dipped in Chinese ink data to realize that Bootloader writes with a brush dipped in Chinese ink renewal in primary processor.
Further, the controller also includes：Recovery of stomge Nand Flash and Bootloader Nor Flash；
Wherein recovery of stomge is connected with primary processor by parallel data grabbing card with Nand Flash, Bootloader Nor
Flash is connected with primary processor by SPI interface.
The Nand Flash are one kind of flash internal memories, and which is internal using non-linear macroelement pattern, is solid-state great Rong
The realization of amount internal memory provides cheap effectively solution.Nand-flash memorizeies have capacity larger, rewrite speed fast
The advantages of, it is adaptable to the storage of mass data.
The characteristics of Nor Flash are nonvolatile flash memory, NOR Flash is performed in chip（XIP, eXecute In
Place）, such application program directly can be run in the Flash flash memories, it is not necessary to again code is read in system RAM.
Wherein, the primary processor is such as but not limited to using ADSP-BF533 process chips.
Recovery of stomge Nand Flash are Nand Flash K9F5608；The Nand Flash K9F5608
It is connected with primary processor by the D0..D7 of data/address bus, which has acted on the binary data stored for used by recovery system,
For data source when system recovery.
Bootloader Nor Flash are Nor Flash M25P20, to deposit the binary system of Bootloader
File is deposited, realize the pointer of program initialization redirect, the function such as hardware initialization, system binary file access pattern.
System can be realized in failure with Nand Flash and Bootloader Nor Flash by the recovery of stomge
Shi Zidong recovers to go back original system, reaches the self-healing purpose of firmware.
Preferably, the processor is connected with controller by CAN.
As shown in figure 3, specific, the controller includes：The CAN interface that is connected with processor, it is connected with the CAN interface
CAN transceiver, the TXD ends of the CAN transceiver pass through the CANTX ends phase of the first photo-coupler and primary processor
Even, the RXD ends of the CAN transceiver are connected with the CANRX ends of primary processor by the second photo-coupler；Wherein, the CAN
Bus transceiver such as but not limited to using CAN transceiver 82C250, such as but not limited to adopt by first, second photo-coupler
Use photo-coupler 6N137.
Buffer action is played to input, the output signal of telecommunication by first, second photo-coupler, to improve CAN signal biography
Defeated reliability.
Embodiment 2
On the basis of embodiment 1, the present embodiment 2 provides a kind of test automobile, including：Described is automobile-used
BootLoader commissioning devices.
After the test automobile installs the automobile-used BootLoader commissioning devices, primary processor BootLoader is simplified
Step is updated, is easy to the test and debugging of vehicle.
