below is the kernel log.
My testbed is DB120 reference borad, of cause it is dual-band.But there is only One works.

I am not sure the cal data area is destoryed or not.
Please help dump that area. I will check it.

#cat /dev/mtdblock5 > /tmp/cal.data

Or you may just let me have a quick view of the cal data for PCI module,
#md 0xbfff5000 10
#md 0xbfff1000 10

I use
   cat /dev/mtdblock5 > /tmp/cal.data
and open the file cal.data, It seems like messy code.

below is the md result under U-Boot of my testbed:

Could you please send the file cal.data to me and let me check it?

It seems the cal data for pci module has been destoryed by you.
Have you ever erase the art partition?
But it's very strange that the cal data for QCA9344 still there.
I am quite confused of that.

do you have gmail??? tell me your email address please.

I think I should tell you something.

My testbed is DB120-Atheros-like board. 9344+PHY8035+9580, 2 pieces of 16M flash(just one for backup).
the original image had been written into the flash.And it runs well 2.4GHz and 5GHz are ok,
Because our own project is ongoing,and we do not want to destroy the original image already on the flash and this method is convenient for debuging work.Thus,we use OpenWrt initramfs.bin,run the image in ram.Then came with that issue--5GHz can not work.

(Last edited by banglang.huang on 31 Jan 2013, 05:59)

I understand your situation.
Could you please share the console log for your original runtime?
I am doubting about QCA9580 can work correctly.

If not convenient put log here, send mail to me at youngchildren@gmail.com.
I also want the file cal.data.

OK , I have already sent the cal.data file and original kernel log to your gmail. Please check it .thx

I have checked you console log for original runtime.
There are two points be noticed,
a. openwrt source code config with 8M flash, while your customized board with 16M flash on board,
b. as you mentioned, calibration data for QCA9582 stored on EEPROM, so please check the openwrt code for restoring cal data. As usually, it fall through among flash, eeprom, otp. You may have a cross comparing of the source code between openwrt and QCA SDK.
