The firmware data to be written is written to the destination address, may include:
S201, mapping relations between the destination address and the data format of the firmware data to be written are established,
And the mapping relations between the destination address and the data format of the firmware data to be written are stored to format mapping
Table；
S202, by the Data Format Transform of the firmware data to be written be binary system Binary file format；
S203, the firmware data to be written after conversion is written to the destination address.
In the present embodiment, the format mapping table can be being also possible to the firmware number to be written of default setting
It is established during carrying out data conversion according to write-in destination address.Wherein, if the format mapping table is will be described to be written
Firmware data write-in destination address established during data conversion, then detailed process may include: according to will be to
The firmware data of write-in carries out the unified conversion of format when destination address is written, for example, the format A for the firmware data being written into
Format transformation C, the format B format transformation C for the firmware data being written into；It establishes the firmware data write-in to be written
Mapping relations between destination address and the data format of the firmware data to be written, and format mapping table is established, it will count
It stores according to the mapping relations between format into the format mapping table.When waiting the reading instruction for receiving the end PC, Ke Yigen
According to the format mapping table of foundation, the destination address of reading is searched, to read firmware data to be read.
It wherein, is binary system Binary file format by the Data Format Transform of the firmware data to be written, and will
Firmware data to be written after conversion is written to the destination address, realizes the unified pipe of all firmware datas to be written
Reason,
It, can easily will be all to be written by address mapping table and format mapping table during specific implementation
Firmware data is unified into the same format write-in, and with can rapidly finding the target that firmware data to be written is written
Location, burning is high-efficient, takes full advantage of the memory space of single Flash, reduces production cost.This programme can be realized firmware

The firmware data of shield, i.e., firmware data to be read, convenient reading realize the unified management of the firmware data to be written.
For example, firmware needed for panel (firmware data) can be uniformly stored in single on SPWB Board
In Flash, the storage of each Code and read-write mode are as follows:
1. register Code Tcon Code is stored in the preset address space Bank D of Flash, the end PC is total by I2C
Line is communicated with Tcon IC, then passes through spi bus read/write address space via Tcon IC (processing unit of firmware data)
Bank D。
2. power management integrated circuit code PMIC Code is stored in the preset address space Bank E of Flash, the end PC
It is communicated by I2C bus with Tcon IC, then passes through spi bus read/write address space B ank E via Tcon IC；
3. parameters of display code PGamma Code is stored in Flash in preset address space Bank F, the end PC is logical
It crosses I2C bus to communicate with Tcon IC, then passes through spi bus read/write address Bank F via Tcon IC；
4. virtual machine code VCOM Code is stored in the preset address space Bank C of Flash, the end PC passes through
I2C bus is communicated with Tcon IC, then passes through spi bus read/write address Bank C via Tcon IC；
5. optical compensation code Demura Cod is stored in the preset address space Bank B of Flash, the end PC passes through I2C
Bus is communicated with Tcon IC, then passes through spi bus address space Bank B via Tcon IC.
The above process makes full use of the memory space of single Flash, by reducing the quantity of external Flash, removing in IC
The integrated ROM in portion, can reduce BOM cost, and all Code are stored in single Flash, realize unified management, read-write side
Just, to improve data-handling efficiency, and without occupying multiple storage units, reduce size reduction cost, improve integrated level, energy
Enough to solve since memory device is many kinds of, firmware data distribution dispersion is not easy to debugging and operational administrative.
