Filling in cyg_flash_devtab[] array

Does anybody know when and how cyg_flash_devtab[] array is filled in? I see &(syg_flashdevtab[0]) == &syg_flashdevtab_end and syg_flashdevtab[0].num_block_infos < 0 whereas SYGHWR_IO_FLASH_DEVICE == ...

Many thanks for so quick reply.

are you sure that your custom driver is included in the eCos configuration? Could there be a# ifdef somewhere that prevents those macros from running?

An easy way I have to find out if a specific part of the source code is compiled, is to voluntarily introduce a syntax error just before of after those macros...

Are you looking at the correct table? From what I'm seeing, the table used by those macros is cyg_flashdev, not cyg_flash_devtab

Yes, the driver is included. I made syntax errors involuntary and it took me about ten attempts to compile the code.

I don't look at the table directly; I see that, in cyg_flash_init function, I have got &(cyg_flasdevhtab[0]) == &cyg_flashdevtab_end (I made debug output) that results in returning SYG_FLASH_INVALID and the message "FLASH: driver init failed: Invalid FLASH address". Any advice?
