Installing OpenWrt on Mikrotik wAP R (RBwAPR-2nD)


#21

I do not have access to serial console right now but here is the initramfs bootlog:

FYC - this unit was LTE kit but I removed the modem before booting into initramfs -- when trying to run sysupgrade with modem installed unit would reboot into RouterOS.


#22

Hm, it looks like SPI NOR flash used is a new one as its ID is not known.
Can you read the full model number from it?

The rebooting issue could be due to PCI power GPIO setting.
But serial is really needed to figure out why does it simply reboot.


#23

This unit is from the recent batch (post April). The model ID from the back is RBwAPR-2nD. FCC ID TV7WAPR2ND. Is this what you were after?


#24

Yes, guessed that. I'm trying to get hardware for serial.


#25

No,I meant to read the full model number from the SPI NOR flash memory.
Its usually 8 or 16 pin IC and often in 25Q something form.
But I need everything to get the JEDEC ID and patch that in.


#26

25Q128JVSM 1748

RBwAPR-2nD__SPI_NOR


#27

OK,will look at it tommorow.
There is a PR for that flash.

Also,support for wAP R was merged couple of days ago but I dont really know how it was accepted since the whole PR simply added the id for wAP R and nothing else.
Its missing a lot


#28

Thank you! Tomorrow I will try to get serial & get to the bottom of PCIe issue.


#29

There is a big chance that OpenWrt does not even get written as SPI NOR flash is not detected as one of the supported ones.
UART should uncover that,but I will make a patched version with that JEDEC ID included


#30

My friend just send me a pic from his older unit, its 25Q128FVSC 1713

RBwAPR-2nD__SPI_NOR_1

However this unit is bricked - so we cannot try it. (Not bricked, more of a toasted!)


#31

That one should be supported as is it an older revision.
The one in your wAP is really new, will push it to Linux-MTD too since the PR author did not.

What happened to that unit?


#32

It was installed in marine environment - water damage under power.


#33

Also,support for wAP R was merged couple of days ago but I dont really know how it was accepted since the whole PR simply added the id for wAP R and nothing else.
Its missing a lot

The things I know are missing are LEDs, reset switch, enabling USB, and enabling PCI. Ethernet works, though.


#34

That is really weird.
As ethernet is initialised in the same way.

This is really hard without having the device


#35

I found these in linux_3_3_5_patch .I'm guessing it's the gpio pin mapping? Other than actually trying each pin, I'm not sure how to tell the different LEDs apart, and I'm not even sure what the control pin is. The reset button?

+		.platform_data = &(unsigned[]) {
+			PLD(user_led, 14, GPIO),
+			PLDI(led1, 12, GPIO),
+			PLDI(led2, 13, GPIO),
+			PLD(led3, 3, GPIO),
+			PLDI(pcie_power_off, 15, GPIO),
+			PLED(control, 10, GPIO, PLED_CFG_INV | PLED_CFG_ON),
+			0
+		},

#36

I already added those into images.
In order to see which LED is which go into /sys/class/leds and manually turn them on one by one and note them


#37

Where would you get the JEDEC ID for the W25Q128JVSM? I can build with the patch and try on the unit


#38

I already made the build with the patch
https://drive.google.com/drive/folders/1w9pgfiC9fhQe9mDl6J4icBeK8LAkO7_S?usp=sharing


#39

Worked very nicely, thank you very much! Do you mind sharing your patch? I'd like to build as well, I am using custom packaged images.
