there are two tables above, tx0-4 is in the first picture.
It is true that other people gave me incomplete information, and there is no 5G configuration. I don’t know where the four antennas are.

aahh.image is stripped off (goes till 0x1e)…i have to click on it to see all.
this is the information I obtained in the discussion group. I will ask if there is any other information to provide to you. In addition, do you have debian wlan0 test code? AP and client. I use hostapd -B /etc/hostapd/hostapd.conf to report errors. I don’t have these configurations yet.

Have not tried yet with mt7615/mt7622. Mt7615 is currently in my r2 (added antenna on wf3 today so i can test 2g4 and 5g). with and without the firmware-file i got a driver own failed…

looks like the error message is added by this patchset: https://www.spinics.net/lists/linux-wireless/msg200710.html
i cannot start AP on wlan0
Could not set interface wlan0 flags (UP): Input/output error
nl80211: Could not set interface 'wlan0' UP
i still have the rfkill-option active (softdep rfkill pre: mt7622)
tried 5.9-main (without the eeprom-patch), same result
seems like it is the rfkill-issue again… i loaded rfkill-module before mt7615e and then i got the firmware-load and can start hostapd
i tried to change the rule because driver-module is named mt7615e instead of mt7622m same result (after reboot). directly after boot i get the driver own failure, if i unload the module and load again, i get the firmware-info…maybe mt7622 is blocked some time

btw. it looks like the eeprom does not get loaded…(ok-message is wrong because on err there is only ret-var set, but not returned). i added the len in brackets to see difference

imho the len is wrong, it is passed to function so i guess it’s the size of full eeprom and sobuffer needs to initialized with zeros till len and then overridden with file-data (or filled after last file-byte)

@nagi have you an idea why driver own failes the first time (also without eeprom-patch - 5.9-main)? without the patch (revert 894b7767ec2fc21574775c354ab5350e51c2171c) i get this:
mt7622-wmac 18000000.wmac: Timeout for driver own
Could you try to uncheck “Bluetooth subsystem support” in make kernel_menuconfig
?
Networking support --> < > Bluetooth subsystem support
Indeed ret does not return, I have modified the above code. You try again:
static int
mt76_get_of_file(struct mt76_dev *dev, int len)
{
char path[64]="";
struct file *fp;
loff_t pos=0;
int ret;
ret = snprintf(path,sizeof(path),"/lib/firmware/mediatek/%s_rf.bin",dev->dev->driver->name);
if(ret < 0)
return -EINVAL;
dev_info(dev->dev,"Load firmware : %s\n",path);
fp = filp_open(path, O_RDONLY, 0);
if (IS_ERR(fp)) {
dev_info(dev->dev,"Load firmware Faile : %s\n",path);
return -ENOENT;
}
ret = kernel_read(fp, dev->eeprom.data, len, &pos);
if(ret < len){
dev_info(dev->dev,"Load firmware ERR, count %dbyte\n",ret);
ret = -ENOENT;
}else{
dev_info(dev->dev,"Load firmware OK, count %dbyte\n",ret);
ret = 0;
}
filp_close(fp, 0);
return ret;
}
As i have compiled bluetooth-support as module i can try to unload it before loading mt7615e module. Should be same,right? bluetooth-module can’t be unloaded…still in use (have unloaded all depencies (mtkbtuart)), but still in use…i guess bluetooth-daemon blocks it. need to drop the revert so i compile and install again without bluetooth.
same result:

@skype, which problem do you mean? i have only the problem with eeprom, where len is larger than the eeprom-file
Indeed ret does not return, I have modified the above, and I provide my test environment:
I don’t understand your above operations very well, because I always ask you for advice and Google search for wifi configuration. You see if you can get close to my test method so that I can help you solve some problems。
I have not used rfkill, nor have I installed it yet. This means that after my configuration starts, I can directly search for wireless AP signals. I provided screenshots.

I will provide my two bin files again, it seems there is no problem at present.
eeprom.c (2.7 KB) mt7615e_rf.bin (1.2 KB) mt7622_wmac_rf.bin (1 KB)
I have found no fatal problems in my current test!
I tested only mt7622 and used eeprom-file from first post of this thread. But also without modifying eeprom.c i have the driver own issue. With bluetooth i can unload mt7615e module and reload it to get it working. Without bluetooth i got always the driver own issue
Could you try my 5.9-mt76eeprom branch to have same config? My buster rootfs is prepared to test bluetooth too,so i have installed those tools.
No problem, I will test it next week. Can you provide your configuration, and I will refer to your config for testing.
you mean my hostapd-config? (works only if not driver own issue appears)
#ctrl_interface=/var/run/hostapd
#ctrl_interface_group=0 # These 2 are just parameters so that the hostap daemon runs.

maybe any patch in my tree may break wifi? these are for bluetooth on r64
the rfkill was previously used to fix the semaphore-issue: [BPI-R64] mt7622 mac80211 WiFi driver
i guess pcie and switch-changes does not affect wifi. strange that you don’t get the ret<len error…
i tried 5.8-main and there firmware is loaded the first time (no driver own issue)…so something is changed till 5.8 and 5.9 causing this issue
@skype which kernel did you use (5.9+)?
I am using linux 5.4.72, your branch.
Ah,ok, i got the driver own issue only on 5.9+,maybe the len-issue is also only there
in my 5.4 i see the semaphore-problem again (imho this was because bluetooth/rfkill)

so eeprom-load on 5.4 works if CONFIG_BT is disabled…else i got the semaphore-error. on 5.9+ i got the driver-own issue and eeprom load failed because len is too big (eeprom-size differently in eeprom_init)
@nagi have you an idea about the driver own issue? It seems not related to bluetooth (like semaphore issue on 5.4).
Mhm,found this https://github.com/openwrt/mt76/issues/438#issuecomment-688114445, but it’s not compatible with my 5.9 source…seems there are Patches missing. but it looks like 5.9.3 has the patch already… => driver own issue fixed in 5.9.3…still have the different len problem…

it looks like this calculation has changed a bit with dc7bd30b97aa (mt76: mt7615: fix EEPROM buffer size), but was also larger than 1k

on entering the mt76_eeprom_init-function i have a len of 19880, so we cannot check again the len…maybe it’s better to check for filesize after read and then fill eeprom-buffer with 0x00
DEBUG: Passed mt76_eeprom_init 127 len:19880
the ret=len imho only works for mtd, if the mtd-partition has same size as eeprom
added a filesize-function and compared the loaded bytes with its return-value…now i got read ok

as i see all have 4 bytes (first 54Mbit,channel1-6,7-10,11-14 as delta). i guess i need to set only the position you’ve mentioned…with delta-bytes=0 all should have same tx-power,right?
is the value directly the dBM (like comment mentiones)?
the defined value 00100110 is then 38dB (in eeprom-file too for all 4 antennas) which seems wrong to me…(26 in front of the line is hexadecimal representation). what is suggested (imho ~21dB) or max value?
also it looks like the eeprom also contain MACs for BT and both ethernet-ports (full mt7622 eeprom)
0x26 decimal is 38, I guess it should be: 38 * 0.5 = 19dBm, the other three parameters should be fine-tuned, so just leave it alone.
I think there should be a Bluetooth address set. I haven’t debugged Bluetooth there. I am not familiar with it. I think I still need to ask you for advice in the future.
why this calculation? or did you get -19dB with the value of 38?
is there an easier way to get the filesize? see my repo i linked before for my current implementation
for bluetooth i did not much except adding some patches, installed bluez and made some basic tests with bluetoothctl
@nagi is there a way to fix the semaphore-issue on (my) 5.4 without disabling CONFIG_BT? i have still the modprobe-config which loads rfkill before mt7622

The power values are in unit of 0.5dBm in registers.

This happens because both wifi and bt share some parts in the wbsys, I haven’t dived into this issue yet.
could you try kernel from my tree? change in build.conf board to bpi-r64 (remove # ), run
in mainline-kernel bluetooth is not working, at least because the scpsys and tty-patch is missing
or use kernels compiled from travis (github-releases)
Btw. I read that set_fs will be limited in 5.10 for some architectures because it can be a security hole. Is there any way to get the filesize without it?
