11.10 Performance
The following chapter lists programming performance for various SPI flash devices.
11.10.1 Performance values
In direct programming mode (J-Link directly connects to the pins of the SPI flash),
the programming speed is mainly limited by the SPI communication speed, the USB
speed of J-Link (if a Full-Speed or Hi-Speed based J-Link is used) and the maximum
programming speed of the flash itself.
For most SPI flash devices, in direct programming mode speeds of >= 50 KB/s can
be achieved.
