Hello
I want to use
https://www.cypress.com/documentation/code-examples/ce224431-psoc-4-uart-printf
on CYPD3171-24LQXQ_pb. Here my steps
1. Modify the Heap size from 0x80 to 0x380 -> build successful
2. Add some code in main.c
#if defined (__GNUC__)
/* Add an explicit reference to the floating point printf library to allow
use of floating point conversion specifier. */
asm (".global _printf_float");
...
#endif /* (__GNUC__) */
Solved! Go to Solution.

Hi ,
CCGx firmware is not support printf directly.
Kindly refer the threads we have been offered in the community to debug the firmware with software UART.
Best Regards,
Lisa

3. Add below in main.c - -> build fail
#include <stdio.h>
4. Add below in main.c -> build fail
int32 integerNum = -212121;
float floatNum = 37.37f;
printf("Testing printf function. long: %ld , float: %f \r\n", integerNum, floatNum);
5. build fail log as below, is it the .text region is not enough to accommodate the printf?
