49.2. Eeprom emulation performance test

49.2.1. Overview

The EEPROM PERF example runs performance testing on simulated EEPROM with 100 data records and 500 records.It’s contain the follow:

config time

format area
write prepared data
test config time

flush time

write prepared data
test flush time

read time

write prepared data
test read time

49.2.2. Board setting

No special settings

Note

Do not write more than one erase size data once
Eeprom emulation needs to be set EEPROM_MAX_VAR_CNT which default count 100 in user_config.h to limit the maximum number of blocks
The relevant writing situation can be viewed by modifying the debug level

49.2.3. Running the example

The serial port output is shown below:
