Support for flash is still missing. Someone is working on a flash chip
for the NAND controller, not exactly for this SoC but for the Core used
in this SoC.  These devices have a serial flash chip and a NAND flash chip.

I am currently working on the PCIe controller.

Thanks for the dmesg dump, I haven't seen a BCM4709 booting, the R6250
uses a BCM4708 with just two PCIe controller.

Thanks for the hint. But this is a bit too much work to be done for just one 
single device I have.

Kind regards,

Sure, you just need to re-write it to don't use 3 abstraction layers
and make it work without Broadcom's SDK specific code.

[OpenWrt-Devel] bcm53xx: Netgear R7000 problems

[Andre Valentin]

Hello!

I saw that there is support for the Netgear R6250 in openwrt. So I thought 
maybe the R7000 is not so far from being support. It's not ;-)
After I modified the R6250 config in openwrt to allow the initramfs image to be flashed. First problem I then saw is that the image loads fine, but on serial I get only rubbish. But the luck was on my 
side, the device responded to ping and allowed me a login.


This is the CFE boot log:
