PSoC6. How to excute FW in SFlash by XIP and write log data or file system in SFlash?

For write data in SFlash we need disable XIP. so it is conflict when excute FW in SFlash.

Is there a walkaround way, I am looking some sample code.

Thanks!

Hello @Max_Li ,

Which PSoC6 device is this and what IDE are you using?

You can find the code example here which demonstrates how you can interface with your QSPI flash in XIP mode: https://github.com/Infineon/mtb-example-psoc6-qspi-xip

Hi Dheeraj,

I see the QSPI_XIP sampe project. it write the flash in smif mode, then chang to XIP mode to excute a function in Flash. It all read access in XIP mode.

The challenge that I met is customer want excute a function in external Flash, it write data to same Flash.

Thanks!

Hello Dheeraj,

I haven't  a solution project.

Write external flash in function like "print_from_external_memory" which located in external flash, can't work. 

/*******************************************************************************
* Function declarations
*******************************************************************************/
CY_SECTION(".cy_xip_code") __attribute__((used))
void print_from_external_memory(const char *buf);

/********************************************************
********************************************************/
void print_from_external_memory(const char *buf)
{
printf("%s", buf);

???write external flash
}
