Hi, Good day!

This is actually my first post here. I’m just starting with the RL78 and I’m using the following:

e2 studio IDE
GCC for Renesas RL78 v4.9.202201
R5F104ML (RL78/G14 Fast Prototyping Board)

I’m configuring the UART and tried to use sprintf() function. However, this error appears:

Error: No room left for const data- the start address exceeds the mirror area. Please move the .text section from lower address to higher address.

I was thinking maybe it’s just because of the project. So I created a new empty project. Initialized the hardware using the code generator but didn’t used any peripherals. I also disabled the WDT.

As you can see, that is the only code I put in the project but I’m still receiving the error. How can I fix it? How can I move the .text section from lower address to higher address? I tried opening the linker_script.ld file and tried modifying it but it doesn’t just work and I’m a newbie to RL78 so I’m not sure if I’m doing it correctly. I tried reading other topics here and in RenesasRulz and it seems like some can use the sprintf() with GCC. That’s why I’m curious why I can’t use it. I hope you can help me with this problem. Thank you!
