load_eprom
The load_eprom utility resides on the teststation. It downloads the core
firmware products into the EEPROM on the Utilities board through the
scan interface. It can also update the JTAG scan interface controller
firmware. If, during a download, it detects any errors, it automatically
retries the download.
The load_eprom utility uses subroutines that perform the following
functions:
• It reads a raw binary file on the teststation.
• It erases the specified Flash sector and verifies that the erase was
successful. It will retry if the erase fails.
• It scan downloads the contents of the binary in 4096-byte page
increments, updating the screen for each page. A “w” is printed
during the write operation, an “r” during the optional read operation,
a “v” during the optional verify operation and a “.” when the page is
complete.
• It can optionally read each page back for verification.
• It can read-verify a binary in the Flash EEPROM and compare it to
the binary on the teststation, without performing the write operation.
The load_eprom utility usage is as follows:
load_eprom -n <IP name> [-QRV] [-P #] [-j|c|e|p|o|t|l|f]
<file>
The options available are given in Table 83.
