- Subject: [ECOS] virtual vectors problem
Hello,
I updated eCos via CVS, then my application two months ago. Since, i noticed
that the comm_channels variable -used to contain the functions pointer on
serial communication channel- is no more in data section but it is in bss
section.
So, when my application is configurated to works in RAM in order to debug
it, i have problem. Indeed, in this configuration i use the option "Inherit
console settings from ROM monitor", but unfortunately the comm_channels
variable is put to zero during the bss initialization consequently, all
subsequent accesses to comm_channels variable cause a hardware reset.
I didn't find anything in eCos sources or in my configuration (ecc file)
which explains this change of location, but to solve the problem i
initialized the comm_channels at the time of declaration : static
hal_virtual_comm_table_t
comm_channels[CYGNUM_HAL_VIRTUAL_VECTOR_NUM_CHANNELS+1]={0};
Anybody, could help me to understand the problem ?
Thank you,
Stephane
