  That's strange... Master bit in Command register still not set.
  Are sure that you have used the latest version of the driver?
  
  Look at the line "PCI Command" in the board log, it contains value 1, but the latest driver version set bit 2 (Master bit) in this register, and now it's value must be 5 (101b).
  
  In this version I've add this peace of code to the init_controller function:

  Code: Select all

             stdcall PciRead32, [ctrl.bus], [ctrl.devfn], dword 4
             test eax, 0x4 ; Test Master bit
             jnz  @f
             or   eax, 0x4 ; Set Master bit
             stdcall PciWrite32, [ctrl.bus], [ctrl.devfn], dword 4, eax
             stdcall PciRead32, [ctrl.bus], [ctrl.devfn], dword 4

  So my question is: are you sure that you have used the latest version of the driver?

Hm... very strange. But ok, I've changed the algorithm a little:

Code: Select all

  .test_master_bit:
           stdcall  PciRead32, [ctrl.bus], [ctrl.devfn], dword 4
           test     eax, 0x4 ; Test Master bit
           jnz      @f
           or       eax, 0x4 ; Set Master bit
           stdcall  PciWrite32, [ctrl.bus], [ctrl.devfn], dword 4, eax
           jmp      .test_master_bit
  @@:

Now it'll try to set the master bit until the win or it will hang the system .

Try this version, please.
