This example provides a description of how to use a DMA channel to transfer a
word data buffer from memory (Flash) to memory (RAM).
The dedicated DMA channel is configured to transfer once a time a 32 word data buffer
stored as constant in the Flash memory to another buffer in the RAM memory.
The received data are stored in the DST_Buffer.
The DMA channel transfer complete interrupt is enabled to generate an interrupt at
the end of the buffer transfer. As soon as the transfer is completed an interrupt is
generated and in the DMA channel interrupt routine the transfer complete interrupt
pending bit is cleared.
The data counter is stored before and after the transfer to show that all data has been
transfered.
TransferStatus gives the data transfer status where it is PASSED if transmitted and
received data are the same otherwise it is FAILED
三星公司官方JTAG下載工具SJF2440源代碼下載。SJF2440 can program SMDK2440 flash memory (K9S1208,Intel E28F128,AMD29LV800BB) through JTAG port and
read/write data from/to a specified address.
Flash中內置了一個狀態寄存器(Status Register,SR)來指示Flash的當前工作狀態和各種操作是否成功。要讀取SR的當前值需要向CUI發送讀狀態寄存器命令(Read Status Register),命令碼為0x70,SR中的內容將在DQ[7:0]上輸出。The Read Status Register (0x70)command causes subsequent reads to output data from the SR until another command is issued. The SR bits are output on DQ[7:0].
This program would work fine only with a specific flash tool through PC printer port under EPP mode.Program is capable of identifying flash chip manufacturer, device type, capacity,... It also allows user to dump flash data, edit/revise the content of flash chip on the Screen, and re-write them back to the chip.
Open Flash Chart is a program for creating charts in Flash to display in Web pages. You can create bar, line, area, and pie charts. It also includes server side classes to help generate the data file used as input. At the moment, there are classes for PHP, Perl, .NET, Java, Ruby (and Rails), and Python
