To read data history from SRAM:
1. From the terminal window press 5. The transaction log is listed.
Copy Data History from On-Board SRAM to SPI Flash Memory
This demo uses both the SRAM and SPI Flash Memory controller modules of the Mini SoC to copy the transaction
history logged to the volatile on-board SRAM to the non-volatile on-board SPI Flash Memory.
To copy data history from SRAM to SPI Flash memory:
1. From the terminal window press 6. The data log is transferred and the terminal indicates “Done”.
Read SPI Flash Memory
This demo uses the SPI Flash Memory controller module of the Mini SoC to read the on-board SPI Flash Memory.
To illustrate the non-volatile nature of the Flash memory, you may power-off the Mini board at any time by discon-
necting both USB cables. Reattach the cables, restart the terminal application, and then perform the memory read
to confirm the data is intact.
To read data history from SRAM:
1. From the terminal window press 7. The transaction log is listed.
Re-Display the Main Menu
During the demo session the main menu will scroll off-screen. To redisplay the menu, press 0.
You may confirm that the SPI Flash memory will retain data in a power-off condition by removing both USB cables
to power-down the Mini board. Rerun the memory read to confirm the data is intact.
While the Mini board is powered, a running log of all transactions is logged to the on-board SRAM.

Note: To clear the Flash memory, press SW1 to reset the Mini board and clear the on-board SRAM. Copy data
history (currently cleared) from the SRAM to the Flash memory.
