Hello,
Our application clears the RedBoot ROM monitor's VVT, because we do not
want to have code executed from ROM (where RedBoot resides).
To be able to read the MAC address out of RedBoot's configuration stored
in flash, I copied code from ecos/packages/redboot/../fconfig.c and
ecos/packages/hal/common/../hal_if.c.
I use a recent ecos.
It works now, but it did not work first because I used the macro's from
ecos/packages/hal/common/../hal_if.h.
This does not work:
CYGACC_CALL_IF_FLASH_CFG_OP_SET(flash_config_op); //add flash config
access function to the VVT
(By debugging, I saw that the entry in the VVT (20) stays empty (NOP).)
ok = CYGACC_CALL_IF_FLASH_CFG_OP( CYGNUM_CALL_IF_FLASH_CFG_GET, \
"eth0_esa_data", \
mac_address, \
6);
I also tried this, but it did not work:
info.key = "eth0_esa_data";
info.val = (void *)&enaddr[0];
info.type = 6;
info.offset = 0;
esa_ok = CYGACC_CALL_IF_FLASH_CFG_OP2(CYGNUM_CALL_IF_FLASH_CFG_GET,
&info);
This works:
hal_virtual_vector_table[CYGNUM_CALL_IF_FLASH_CFG_OP]=(CYG_ADDRWORD)(flash_config_op);
esa_ok = flash_get_config("eth0_esa_data", &enaddr[0], 6);
So I'm curious to know why the macro's from
ecos/packages/hal/common/../hal_if.h do not work.
Kind regards,
Jürgen
