Subject: [ECOS] Filling in cyg_flash_devtab[] array
Date: Fri, 13 Dec 2013 08:29:00 -0000 [thread overview]
Message-ID: <1386923355115-254547.post@n7.nabble.com> (raw)
Hi everyone!
I suppose my question is easy for those who know eCos.
I tried to write driver for flash device. Following the manual, I wrote
/ DEVIO_TABLE(
p8p_handlers,
p8p_write,
p8p_read,
p8p_select,
p8p_get_config,
p8p_set_config,
p8p_close
);
DEVTAB_ENTRY(
p8p_label,
p8p_name,
0, //does not depend upon a lower level interface
&p8p_handlers,
p8p_init,
p8p_lookup,
p8p_priv
);/
in p8p.c and created such a flash_p8p.cdl:
/cdl_package CYGPKG_DEVS_FLASH_P8P {
display "P8P FLASHlike memory support"
parent CYGPKG_IO_FLASH
description "FLASHlike memory device support for P8P"
implements CYGHWR_IO_FLASH_DEVICE
hardware
compile p8p.c
}
/
I added my package in ecos.db and built it alright. However, RedBoot tells
me: *FLASH: driver init failed: Invalid FLASH address*. I see
&(cyg_flashdevtab[0]) == &cyg_flashdevtab_end, so, cyg_flashdevtab[] seems
empy, right? Why may that be?
TIA
