1.3.4.2 Download speed
The following table lists performance values (Kbytes/s) for writing to memory (RAM):
Hardware
Rev. 1 via USB
Rev. 1 via TCP/IP
Table 1.4: Download speed differences between hardware revisions
All tests have been performed in the testing environment which is described on Mea-
suring download speed on page 208.
The actual speed depends on various factors, such as JTAG/SWD, clock speed, host
CPU core etc.
