Assuming that the Image Tool on PC is Server, which sends images files to AmebaZ(Client) through UART.
Client or Server, whichever starts first will be ok.
Steps to start client are as following, which will get AmebaZ into UART_DOWNLOAD mode.
(1) For QFN32, pins marked with “1” on the figure should be connected by jumper cap.
For QFN48 & QFN68, pins marked with “2” should be connected by jumper cap.
(2) Push the Image Download Button and keep it pressed
(3) Power on the board or press the Reset Button. Now AmebaZ get into UART DOWNLOAD mode
(4) Finally Release the Image Download Button. Now the client is ready for receiving data.

Steps to start Server are as following:
(1) Select serial port and transmission baudrate. The default baudrate is 1.5Mbps.Then open serial port
(2) Select the images to be transferred and input addresses. The address which starts with 0x08 is for flash,
and 0x10 for RAM
(3) Click Download button to start. Now the server is ready to send data.
When the client and server are both ready, data transmission begins.
The progress bar will show the transmit progress of each image. You can also get the message of operation
successful or errors occur from log window.
