I want to erase spi flash memory using linflash api or flash.h. I have written small program which is given below.#include #include #include #define MAX_PSIZE 256/* initializers defined in XN file* and available via platform .h */ fl_SPIPorts SPI = { PORT_SPI_MISO , PORT_SPI_SS , PORT_SPI_CLK , PORT_SPI_MOSI , XS1_CLKBLK_1 }; fl_BootImageInfo b;int main () {/* main application - calls upgrade* to perform an in - field upgrade */ fl_connect ( SPI ); fl_deleteImage(b); fl_disconnect (); return 0;}when i build the program it gives error that Undefined reference to 'fl_connect' ,Undefined reference to 'fl_deleteImage', Undefined reference to 'fl_disconnect'. and also how delete spi flash memory using command prompt?

you are getting errors because, the library flash is not being recognised. You need to add the flash in your application Makefile as shown below:XCC_FLAGS = -g -O3 -lflashYou can get more details about library flash APIs from the following link:https://www.xmos.com/support/xtools/doc ... 0Pr...Also, have a look at the xflash command line manual:https://www.xmos.com/support/xtools/doc ...
