FSL PCIe controller drivers before REV 3 has this test for link up: enabled = ltssm >= PCI_LTSSM_L0;
We have a PCIe dev. that stays in LTSSM=0x51 (Polling Compliance) when non ready for PCI transaktions. When FSL PCIe controller tries to access this device, it hangs forever. Is LTSSM=0x51 really a "legal" state for link up? If not, what is a suitable range(maybe LO <= ltssm <= L0s(0x27)) ? Jocke BTW, the same test is valid in Linux too. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
