8) Send each byte in the line to the bootloader app in the camera over the UART.
9) When one line is sent, wait for an ACK byte (0x00) from the camera.
10) Repeat steps 7 & 8 until all lines are sent. The 8 th and 9 th bytes of each line contain a “line
type” descriptor. The last line in the file has a descriptor value of 0x0001. The host app
as well as the bootloader will terminate after processing the last line.
Shown below is some sample code in C which performs the Host uploading process;
The ReadLine() function reads a single line of data from the hex file into a buffer (CharBuff) but
does not include the <CR> and <LF> bytes. It returns the character count of the buffer. Each byte
in the line is sent to the camera. Since the camera expects a <CR> at the end of each line,
TransmitBuffer[0] is loaded with this value and sent as the final character of each line. The routine
keeps track of the line type descriptor (line_type) and terminates after the last line has been sent.
