I'm trying to create my own bootloader for the TM4C129 processor. When i'm currently in the monitor program, I can easily ask the monitor to switch into the bootloader, but after i entered the bootloader program, i'm not able to find the device again. For sending and receiving bytes with the target device, I'm using the I2C interface and I think that this problem is related to a wrong configuration of it.
My problem is that I don't exactly know, how to configure the I2C interface in order to be able to send commands to the target device.
Is the master required for sending commands to the target device, while it is in the bootloader program?
Could someone give me an example on how to configure the interface in C?
Best regards,
Daniel
