you have an bpi-r64, right? not the reference-board or the elecom…

then you need to look in the mt7622-bananapi-r64.dts if the pcie0/1 are enabled. show us output of lspci

72

lspci is empty. I had to recompile once again to include busybox.

mt7622-bananapi-bpi-r64.dts is as follows.

Dts looks right…from your dmesg it looks like both ports are down…maybe something power-related? Can you compare your dtsi with mine (5.4-main branch except switch driver)? Have you added the other patches i’ve mentioned (irq handling, class fix)?

74

Looks like I found the culprit.

I just needed to apply all four patches from Spilt PCIe node to comply with hardware design series. I had to make some modifications as I mentioned above since mt7622-rfb1.dts from OpenWRT is a little bit different from what the patch is expecting (see attachments).

1002_1-dt-bindings-PCI-Mediatek-Update-PCIe-binding.patch (9.0 KB)

1002_2-mediatek-Use-regmap-to-get-shared-pcie-cfg-base.patch (2.7 KB)

1002_3-Split_PCIe_node_for_MT2712-MT7622.patch (7.9 KB)

1002_4-ARM-dts-mediatek-Update-mt7629-PCIe-node.patch (2.0 KB)

BTW is there a more elegant way of obtaining these patches rather than select - copy - paste to text editor - save as .patch - put in patches-5.4 dir?

Two things bother me though.

  1. For some reason OpenWRT generated config files in such a way that radio0 is wlan1 and vice versa.
  2. Txpower on both cards seems to be limited to 6 dBm. Is there a way to increase it?

Nice to see there is an official patch now…i got them here or by email and collected over time :slight_smile:

I don’t know if openwrts build-system can handle mbox files…then you can click “series” button in the upper right corner if patchwork site to download a “git am” compatible file with all patches from the series

Maybe you can change that by modifying udev-files.

There is a discussion about the 6dbm issue,but afaik no working solution…here is a hint why this happens,but afair patch was bot accepted and maybe not compatible with mainline code

76

@svintuss As for 6dbm limit. Compile mt76 driver with eeprom.c from git on top of this thread. This is working for me on mt7622. I do not have 7615 so cannot check.

After replacing eeprom.c mt7615 is non-functional: It became a clone of mt7622 device (same MAC, system thinks it’s 2.4 GHz).

Compare this output to my previous post: ifindex, wdev and addr are different.

I’m sure this is because the fixed eeprom-data in mt76_get_of_eeprom called for every device handled by the driver

Do you see your mac-address? :grin:

This function should be called only for mt7622 wifi and not mt7615…

If i see this you see that with the eeprom-data all cards will be handled as 7622 because of first 2 bytes

You need something like this in mt76_get_eeprom function:

switch (mt76_chip(dev)) {
    case 0x7622: /*here existing content*/ break;
    case 0x7615: /*eeprom data for 7615*/ break;
}

But make sure function returns 1 else it will break mt76_eeprom_init…

Thank you, @frank-w. Do you have any ideas where can I get eeprom data for 7615?

@niebieski20 where did you get mt7622 eeprom?

80

You can skip the eeprom part for mt7615 in a first step (only write eeprom data for mt7622) but let function return always 1. I guess he used the eeprom-data normaly written to mtd partition in openwrt

have modified eeprom.c like i’ve mentioned…

eeprom.c (7,3 KB)

Thank you.

Am I getting this right?

Can images from this post be of any help in extracting mt7615 eeprom? Full support for mt7615 WiFi is claimed.

lspci in this LEDE image looks like this.

basicly yes, but i have renamed the data-const and moved outside the switch for better readability. also the ret-lines can be merged to int ret=1; or easier “return 1;” as replacement for the 3 lines

i think you do not need any additional eeprom-data, because card should have it’s own burned onto it. i had also used mt7622 without any additional eeprom-data, but i have no mt7615 which may breaḱ and have not yet looked at the 6dbm-issue (i guess eeprom-data is fix for this)

Ok, so this is what I came up with.

static int
mt76_get_of_eeprom(struct mt76_dev *dev, int len)
{

	static const u8 eeprom_mt7622[] = {

	switch (mt76_chip(dev)) {
    		case 0x7622: /*write eeprom data for 7622*/ 
			memcpy(dev->eeprom.data, eeprom_mt7622, 0x400);
			break;
    		
		case 0x7615: /*write eeprom data for 7615*/ 
			break;
		};


	return 1; // this part makes the function to always return 1, right?

}

As a result I should have mt7622 working on 20dBm and mt7615 functional but limited to 6dBm, right?

right, just try it out…i have not yet tested it…

Thanks, I’ve got mt7615 functionality back, but it’s still limited to 6dBm.

Hello all. I took a break from further experimentation to get the BPI MT7615 PICe card working on my BPI R64 rev 1.1. I was able to get the 2020-05-08 update ,Debian10 with kernel 5.4.0 installed on eMMC and the MT7615 is working somewhat satisfactorily with it.

I am trying to keep the MT7622 and DRAM chips cooler using a 5V fan (extracted from an old laptap). Can someone help me how to control the fan speed using PWM? I have hooked the fan to the fan socket (which is besides the WPS switch), but presently it runs at full speed. The schematic shows FAN_OUT has different labels: GPIO97/PWM_CH3/TXD4 or G12, PWM3 I don’t know exactly how to try out different PWM duty cycles from the command line. I will eventually do it programatically.

I can start a new topic to discuss this request if it is not appropriate here.

A new topic discussing about the pwm would be better and created it [BPI-R64] PWM-support

Thank you for starting the new topic. I’ll repost my previous message there.
