<html><div style='background-color:'><DIV class=RTE>HI!</DIV>
<DIV class=RTE>i am working with eepro driver on mips processor with my out own manufactured PCI controller. we have been able to configure card get it's configuration space and read etc. When driver is loaded eeprom checksum is passed but self test is gets failed. When is dig it down to bit level i noticed there are two lines before self test in driver</DIV>
<DIV class=RTE>&nbsp;</DIV>
<DIV class=RTE>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; self_test_results[0] = 0;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; self_test_results[1] = -1;</DIV>
<DIV class=RTE>&nbsp;</DIV>
<DIV class=RTE>Now when</DIV>
<DIV class=RTE>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outl(tx_ring_dma | PortSelfTest, ioaddr + SCBPort);</DIV>
<DIV class=RTE>statement is executed which i&nbsp; think may be changing both&nbsp; self_test_results[0] and&nbsp; self_test_results[1] that is total of 8 bytes.</DIV>
<DIV class=RTE>But when i return from this statement STATUS register in my controller states that master abort has occured and through debugger when i print the values of self_test_results[0] and&nbsp; self_test_results[1]&nbsp; then </DIV>
<DIV class=RTE>&nbsp;</DIV>
<DIV class=RTE>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;self_test_results[0] = 0x4f4518b;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; self_test_results[1] = -1;</DIV>
<DIV class=RTE>which means that IO has been done on self_test_results[0] that now contains checksum but nothing has been done to self_test_results[1] , that's why checksum fails.</DIV>
<DIV class=RTE>Is this the problem of my settings in controller register? Is my controller is not dealing with multibyte transfers? can anyone guide me&nbsp;through this problem.</DIV>
<DIV class=RTE>One thing more does PortSelfTest bit in outl means that card will transfer data on multiple bytes i.e. self_test_results[0] and self_test_results[1] .</DIV>
<DIV class=RTE>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; regards</DIV>
