Coreboot hangs with post code 0x75. How to describe the PCIe Switch (Asmedia ASM1182e) and devices connected after it for devicetree.cb?
I'm trying to develop a coreboot+seabios for motherboard MB-7573 by LANNER, CPU Intel(R) Atom(TM) CPU C2758. PCI root port 4 configured as x4. PCIe Switch (Asmedia ASM1182e) connected to root port 4. Two more devices are connected to ASM1182e - Xillinx network device and RDC C6139(PCI bridge & VGA). How to describe the PCIe Switch (Asmedia ASM1182e) and devices connected after it for devicetree.cb?
Link to Asmedia ASM1182e: http://www.asmedia.com.tw/eng/e_show_products.php?cate_index=168&item=13...
My version of devicetree.cb not work and coreboot hangs on post code 0x75 (POST_BS_DEV_INIT):
device domain 0 on device pci 00.0 on end # host bridge device pci 1.0 on end # PCIe Port #1 x4 device pci 2.0 on end # PCIe Port #2 x4 device pci 3.0 on end # PCIe Port #3 x4 device pci 4.0 on subsystemid 1b21 1182 device pci 0.0 on subsystemid 1b21 1182 device pci 03.0 on subsystemid 10ee 2012 end subsystemid 1b21 1182 device pci 07.0 on subsystemid 17f3 1035 device pci 0.0 on subsystemid 17f3 2200 end end end end # PCIe Port #4 x4
Hangs on init_link function (POST_BS_DEV_INIT=0x75). coreboot/src/device/device.c
static void init_link(struct bus *link) { struct device *dev; struct bus *c_link;
for (dev = link->children; dev; dev = dev->sibling) { post_code(POST_BS_DEV_INIT); post_log_path(dev); init_dev(dev); }
for (dev = link->children; dev; dev = dev->sibling) { for (c_link = dev->link_list; c_link; c_link = c_link->next) init_link(c_link); } }
More visually device tree so:
