Working with the FLASH programmer
PEEDI has built-in universal FLASH programmer. The programmer is used through the flash CLI
commands.
The programmer can program FLASH chips in two ways:
1. Directly - completely non intrusive, no target memory is used, but very slow.
2. Using small agent program which is downloaded to the target RAM (1KB) and uses
configurable data buffer (0.5-64KB).
So you can choose which is best suitable for your needs, but keep in mind that the "agent" method
is much faster. The programming method is set in the FLASH section of the target configuration
file, where the configurations are available - DIRECT, AGENT and AUTO - where first agent is
tried, if failed the direct method is used.
The image to program is not buffered to the PEEDI's RAM, but it is downloaded from a
TFTP/FTP/HTTP server or a MMC/SD card and programmed in configurable data blocks (0.5-
64KB), which means that there is no theoretical maximum size limit of the image to be
programmed.
Using the programmer you can:
•
program the FLASH chip
•
verify the FLASH chip
