Hello,

I used example ETHCAT_FWUPDATE_SSC_APPLICATION_XMC48 to be able to update my Application on an XMC4300 via EtherCat.

My application started with the following Flash setting:

• 1. first 64kB for Bootloader (0x0C000000 -0x0C010000)
  
• 2. second 64kB for ErtherCatEEPROM (0x0C010000 -0x0C020000)
  
• 3. APP Code from 0x0C020000 -0x0C035000
  
• 4. Backup Buffer 0x0C035000 -0x0C040000
  

If I try set Bootloader in the first first 16kB or also 32kB its not working anymore. I changed following things: (for Bootloader size of 32kB)

• linker_script.ld : memory and ABM Header Position

• reduced the #defines for the max size of Code
  for example : #define APP_PARTITION_MAX_SIZE (128 * 1024)
  
• Did not chang App Code position or Backup

Hello, I have been experiencing the distance2go development board recently, and I have had some problems, such as how to read the signal using the uart port of the distance2go Development board, what is the baud rate, how to set it, and how to burn the program using the UART port.
