I discovered(to the truth,I dicovered previously) received data upsidedown. Please refer to 809-line in last-sent output log
Whereas host sends. 0000 ff ff ff ff ff ff 00 15 c5 6d 23 f0 08 06 00 01 ........ .m#..... 0010 08 00 06 04 00 01 00 15 c5 6d 23 f0 ac 10 01 1c ........ .m#..... 0020 00 00 00 00 00 00 ac 10 01 1c ........ ..
I thought I could amend this and I amended(I thought) like next in \packages\devs\eth\smsc\lan91cxx\current\src\if_lan91cxx.c. (I risk of appearing stupid but I henestly tell what I did.) cyg_uint8 get_data_byte(struct eth_drv_sc *sc) { //20070919 int sf;
cyg_uint8 c; struct lan91cxx_priv_data *cpd = (struct lan91cxx_priv_data *)sc->driver_private;
// //20070919 // db_printf("cpd->data_pos=%d rxd_t=%d\n",cpd->data_pos,sizeof(rxd_t));
if( cpd->data_pos == sizeof(rxd_t) ) { cpd->data_buf = get_data(sc); cpd->data_pos = 0; //20070919 sf = 1; } //20070919 begin else{ sf = 0; } //20070919 end
//20070919 begin //ORG c = (cpd->data_buf>>(cpd->data_pos*8))&0xFF; c = (cpd->data_buf>>(sf*8))&0xFF;
// //20070919 // db_printf("cpd->data_buf=%x c=%x\n",cpd->data_buf,c);
After that I ran and stored output log(I send gzip file). To my astonishment,I found RxEvent errored. Please refer to 795-line. RxEvent - bad rx: stat: 0x7f40, len: 0x41fa
Apparantly I wrongly concocted. I am still tracing source but I haven't found smart answer. Even if I thought I could have corrected it myself, I worries that my bad coding affects anywhere else.
Please teach me how to best amend this behaviour. (I am afraid this time also I am missing target.)
I would appreciate your reply. Thanks in advance.
