Subject: Re: [ECOS] system ASSERT problem
I got strange problem with my application. When I compile system with
global compiler flags
-ml -m4 -O2 -Wall -Wpointer-arith -Wstrict-prototypes -Winline
-Wundef -Woverloaded-virtual -ggdb -ffunction-sections
-fdata-sections -fno-rtti -fno-exceptions -fvtable-gc -finit-priority
-save-temps
I got info on terminal:
ASSERT FAIL: <3>mcard.c[193]int mcard_write_bmask() Valid card
handler required
ASSERT FAIL: mcard.c [ 193] int
mcard_write_bmask()
Valid card handler required
But when I remove '-O2' flag the problems doesn't occur. What can be
the problem???
There is no mcard.c in the repository, so i guess it is something you
have added. Without the code it is hard to guess what is happening.
Below is the code that generates the ASSERT:
int mcard_write_bmask(mcard_t *card)
{
CYG_CHECK_DATA_PTR(card, "valid card pointer required");
CYG_CHECK_DATA_PTR(card->bmask, "valid mask pointer required");
CYG_ASSERT(card->mcard_hdl,"Valid card handler required");
if( !card->mcard_hdl ) return -EINVAL;
if( !card->bmask ) return -EINVAL;
int e;
e = mcard_verify_card(card);
if( e ) return e;
e = cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_LOCK,0,0);
if( e ) return -EIO;
cyg_uint32 address = card->header.bmask_offset;
cyg_uint32 len = sizeof(cyg_uint32);
cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_WRITE_POS,&address,&len);
len = card->header.bmask_size;
e = cyg_io_write(card->mcard_hdl,card->bmask,&len);
cyg_io_set_config(card->mcard_hdl,CYG_IO_SET_CONFIG_CARD_UNLOCK,0,0);
if( e ) return -EIO;
return ENOERR;
}
**************************
and the mcard_write_bmask function is called from function below:
typedef struct mcard_t
{
cyg_io_handle_t mcard_hdl;
mcard_header_t header;
mcard_bmask_t *bmask;
cyg_uint8 opened;
} mcard_t;
int I::formatCard()
{
int e;
mcard_t mcard;
mcard.mcard_hdl = 0;
e = mcard_open(&mcard);
if( e ) return -1;
MCARD_PRINT_HEADER(&mcard.header);
CLEAR_BUF(mcard.bmask,mcard.header.bmask_size);
e = mcard_write_bmask(&mcard);
if( e ) return e;
MCARD_PRINT_BMASK(&mcard);
mcard_pdata_t pdata;
CLEAR_BUF(&pdata,sizeof(mcard_pdata_t))
e = mcard_write_pdata(&mcard, &pdata);
if( e ) return e;
MCARD_PRINT_PDATA(&pdata);
return 0;
}
