  1. I am following your steps and doing the same process here since I use a .dtb khadas different from yours. I'll post the results, sorry for the delay in responding. Thank you for sharing the method used. in my case I just need to change the wifi in the tree change the driver used by the kernel really my card is not broadcom BCM4330, I believe it is AP6330. I will try to figure out how to make it load the correct fimware once the kernel driver is the same for both wifi cards brcmutil brcmfmac I need to make him load the AP6330 fimrware then we will have a correct dtb for this card. Give me your
  2. As a certainty it is not my case because I did not design the projects. But I want to go the way you described the details so well. I think I understood the majority thanks a lot for describing, it gave a better idea of how things work. Thank you very much for your time. I intend to use as a model meson-gxl-s905x-khadas-vim.dtb, because the 3 amlogic that I have work with this model differ only in wifi and bt. many plates arrive in Brazil like these, I believe because they must be very cheap. I would like to do the dtb in the correct way. I can try I would be very happy if I did this job. I do
  3. Yes, I'm Brazilian from Curitiba. I was surprised to see someone from Brazil here ... How did you access the data on Android. I try to mount the partitions and it is not possible. And installing shell as root on my boxs905's Android, I don't have access to the kernel folders or firmware. I thought about using the dd command and creating an image and mounting with mount -o loop android.img / mnt. Can you describe how you did it ...... I'm interested and get the Android firmware, just like you did...... root@fenix:/home/fenix# cd / root@fenix:/# mount /dev/mmcblk1 /mnt/ NTFS sign
  4. Yes. You are absolutely correct. My device tree is shown below. the dtb file can be transformed into dts and edited and recompiled, but unfortunately I don't know how to do this, I would love to learn. This would be the correct way to do it. Because my dtb file is wrong and we changed the firmware because of this. Do you have any idea how to do this........... my file .dtb used dtb_name=/dtb/meson-gxl-s905x-khadas-vim.dtb I will convert it to dts and pass the file to try to fix and make a new dtb in the correct way to help other users. I will send the
  5. I did as you said, I restored the default firmware, it stopped working again, only the master version in development works. Thank you.

  6. the solution is further down this forum, I am Gilberto and staff helped me solve this problem .....
  7. thanks for the guidance I managed to make it work just below the topic ...
  8. Finally wifi worked broadcom 4330, can scan the network, step everything below, described by the great friend dbsharpe. It was just a firmware update. Without help it would be very difficult to know. I need to learn to think in order to solve other similar things. I really appreciate everyone's help. Because the latest 5.7.0-rc7 kernel does not have compatible firmware, it would be really nice to have a script to update them automatically. I believe that there is otherwise I could make one to collaborate. root@arm-64:/home/fenix# cd /lib/firmware/brcm/ root@ar
  9. unfortunately it didn't work, i don't know if i did something wrong. the dmesg command shows errors in the kernel, my last attempt is to copy the android firmware as it works the same. kernel messsages [ 22.112863] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4330-sdio for chip BCM4330/4 [ 22.113049] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available [ 22.116751] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4330/4 wl0: Oct 25 2011 19:34:12 version 5.90.125.104 the other errors is [ 35.332338] i

  11. I'm trying to open the box and take a picture of the shipset wifi, I don't want to destroy it. I will lose the warranty. the chipset appears to be..... Broadcom BCM4330 https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx To check the status of wireless card, run rfkill list nothins is blocked hardware and software ok I am not an expert, as there are drivers that cannot work at 5Ghz only at 2.4Ghz, perhaps changing the search channels. or the wifi region with the command The current regdomain can be set to the United States wit
  12. broadcom bcm4330 is chipset I tried many drivers sudo modprobe b43 sudo modprobe wl sudo modprobe brcmsmac brcmsmac , only this driver works and finds the device wlan0 but does not scan the network, I thought about a wifi region and use wpasupplicant but it didn't work! I will try use the windows driver by ndiswrapper !!!! I found some information here: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
  13. thank you very much for responding, I did the procedure below for my wlan0 device is gone(disapear) To fix, use mv /lib/firmware/brcm/brcmfmac4330-sdio.txt /lib/firmware/brcm/brcmfmac4330-sdio.txt.old ln -s /lib/firmware/brcm/nvram_ap6330.txt /lib/firmware/brcm/brcmfmac4330-sdio.txt in a shell on the target as root. Not sure where this Ubuntu distribution fault has crept in. nvram_ap6330.txt is actually the same file as android system:/etc/wifi/40183/nvram.txt and although not perfect, works better! root@arm-64:/home/fenix# ifconfig eth0: flag
  14. staff can help me ?, I have a project in Brazil(www.sistemafenix.com.br) and replace my raspberry with amlogic s905. I have had many problems with wifi. I bought 30 boxes. Below I present the information find the wifi but do not find any wifi network. With the ifconfig command I was able to view wlan0 but found nothing with the command: This is the last version: root@arm-64:/home/fenix# uname -a Linux arm-64 5.7.0-rc7-arm-64 #20.05.6 SMP PREEMPT Fri Jun 5 20:29:42 MSK 2020 aarch64 aarch64 aarch64 GNU/Linux root@arm-64:/home/fenix# root@arm-64:/home/fenix# ifconfig e
  15. I am sorry you are right, I just wanted to help I discovered this in my research. The company making the SV6051P wifi chip went bankrupt. So you won't get any new Android OS with that driver or old ones where the driver didn't exist. Linux kernel developers also said they won't update the driver for newer kernels and mainline it because it's in a terrible state and it must go extinct. It's a very bad idea to buy such no-name devices, now later on you sit with problems.
