11.4.2.1.3 Perform blank check
If this option is checked, a blank check is performed before any program operation to
examine if the affected flash sectors are completely empty. The user will be asked to
erase the affected sectors if they are not empty.
11.4.2.1.4 Skip blank areas on read
If this option is checked, a blank check is performed before any read back operation
to examine which flash areas need to be read back from target. This improves perfor-
mance of read back operations since it minimizes the amount of data to be trans-
ferred via JTAG and USB.
11.4.2.2 Logging
You may set some logging options to customize the log output of J-Flash SPI.
11.4.2.2.1 General log level
This specifies the log level of J-Flash SPI. Increasing log levels result in more infor-
mation logged in the log window.
11.4.2.2.2 Enable J-Link logfile
If this option is checked, you can specify a file name for the J-Link logfile. The J-Link
logfile differs from the log window output of J-Flash SPI. It does not log J-Flash SPI
operations performed. Instead of that, it logs the J-Link ARM DLL API functions called
from within J-Flash SPI.
