Floating point error in tuner_r82xx.c

Hi, I get a floating point exception when I run rtl_tcp. I traced the error with GDB to line 515 of tuner_r82xx.c if (vco_fra > (2 * pll_ref_khz / n_sdm)) I found that n_sdm was 0. I don't understand how this code work and I'm very new to this software but it sure looks like a programming bug. | 513 /* sdm calculator */|| || 514 while (vco_fra > 1) {|| || 515 if (vco_fra > (2 * pll_ref_khz / n_sdm)) {|| || 516 sdm = sdm + 32768 / (n_sdm / 2);|| || 517 vco_fra = vco_fra - 2 * pll_ref_khz / n_sdm;|| || 518 if (n_sdm >= 0x8000)|| || 519 break;|| || 520 }|| || 521 n_sdm <<= 1;|| || 522 }| If the condition on line 515 ever evaluates to false then vco_fra doesn't get updated. The loop will keep repeating with the same value of vco_fra until n_sdm becomes 0. Steve
