Hi!
I've a network module with a MK64FX512VLQ12 microcontroller that shall read and write data to an external flash-memory and present it on to a webpage. It does so using SPI-communication on channel "spi2:2".
This works perfectly fine while running in debug-mode and I can surf in to the card and see the data as expected. However, as soon as I download the release code and reset the microcontroller the SPI-communication somehow makes the program work improperly and I am not able to even surf on to my webpage.
If I comment out the following piece of code in my SPI-setup function:
m_Device = fopen("spi2:2", NULL);
then the release code also runs and works normally and I can surf in onto my webpage (without any data-displayed from the memory of course) so there is something happening when trying to establish the SPI-communication.
I do not now how to debug it because when I run with debugger it works fine..
One thing I've done is that in the commented out:
//do not initialize { section .flashx };
Because I got this error:
Error[Lp005]: placement includes a mix of sections with content (example "initializers for USER_DEFAULT_MEMORY") [suitable for placement in ROM] and sections without content (example "ro data section .flashx in vectors.o(bsp.a) symbols: [__FLASHX_START_ADDR]") [suitable for placement in RAM] C:\Arm\PL-ETH_Arm\LinkA_K64.icf 78
In the linker file (see attached file).
I do not know the reason for this error either... Anyone with ideas on what's going on?
All help is appreciated!
Regards,
Elias
