can you inform me of the meaning of PCIE ERROR CODE?

I.MX8MQ  does  not work with QCA9882 Wifi Module via PCIE #0 bus 

we can not find the description of PCIE Error code in I.MX8M  Reference Manual.

Hi JungHwan

 

from log "Phy link never came up" this may be hardware issue.

One can try other pcie cards and check hardware using pcie recommendations provided in

i.MX 8MDQLQ Hardware Developer’s Guide

 

Best regards

Great Thanks !! 

 

We want to know what the  PCIE Error Code  means. 

in case of PCIE Link Failure, 

why the  Register PCIE_PORT_DEBUG1  Value remains 08000000  while trying to link up ?? 

 <=  VAL #### 3 # 08000000# 

 

logging from dw_pcie_link_up function.  

int dw_pcie_link_up(struct dw_pcie *pci)
{
u32 val;

if (pci->ops->link_up)
{
dev_info(pci->dev, "zzzzzzzzzzz ## 1 ## Link up\n");
return pci->ops->link_up(pci);
}

//dev_info(pci->dev, "zzzzzzzzzzz ## 2 # %016X# Link up\n", pci->dbi_base );
val = readl(pci->dbi_base + PCIE_PORT_DEBUG1);
dev_info(pci->dev, " dw_pcie_link_up # VAL #### 3 # %08X# \n", val );
return ((val & PCIE_PORT_DEBUG1_LINK_UP) &&
(!(val & PCIE_PORT_DEBUG1_LINK_IN_TRAINING)));
}
