Uboot problem #57

Closed de-conf closed 5 years ago

de-conf commented 5 years ago

I am very sorry for disturbing you! ! But I am now very interested in this! ! I want to start usb-storge directly from uboot！ But I saw what you wrote before. USB3 works but not for the rootfs boot drive due to a u-boot limitation. Once the kernel is up the USB3 driver is loaded. it's here I found that the u-boot of the wrt ac series is done by you!

I want to know the details about how to build the u-boot

And can solve this bug? Why am I obsessed with starting the kernel of usb? When the kernel is above the flash, the kernel after startup is still flash, My operation can't affect the kernel.I don't know what to do Looking forward to your reply!

Excuse me, I'll answer. Maybe this will help you, instead of USB3 use the SATA/USB2 port, it is supported from U-Boot.

Glad to your answer, do you mean uboot support for booting rootfs from usb 2.0?

Sorry, ask again how to start rootfs using the uboot command? Do I need to change uboot env var? What is it? I tried the following command and the result could not be started.

Setenv nandboot 'scsi init;ext4load scsi 0:1 $defaultLoadAddr kernel;bootm $defaultLoadAddr'
Setenv altnandboot 'scsi init;ext4load scsi 0:1 $defaultLoadAddr kernel;bootm $defaultLoadAddr' 

saveenv

Yes, take a look - https://github.com/ValCher1961/McDebian_WRT3200ACM/wiki/%23-Using-external-drives-in-U-Boot

Thank you for this great work, I will experiment with him right away! Thank you very much for your answer! !

ValCher1961 commented 5 years ago

Ok!

de-conf commented 5 years ago

Ok!

Take the liberty to ask, can you explain the uboot build steps? I am very interested! I have downloaded eldk

ValCher1961 commented 5 years ago

Sorry, no, I was not able to collect U-Boot :(

de-conf commented 5 years ago

Sorry, no, I was not able to collect U-Boot :(

It's ok, anyway. Thank you for your help! !

A small remark, format the disk with the command - mkfs -t ext4 -O ^64bit -L kernel /dev/sda1, because U-Boot does not work with 64bit.

Ok, thanks for your reminder, I am watching your wiki

I noticed that your kernel is specific, can I use the official kernel?

Linksys and OPENWRT cannot be used only from Chadster or similar ones that download Linux from disk.

Not quite understand! Language differences, I can't understand after translation. In addition, I have a problem, uboot can not read usb part details as following:

Marvell>> usb info 
1: Hub,  USB Revision 2.0
 - u-boot EHCI Host Controller 
 - Class: Hub
 - PacketSize: 64  Configurations: 1
 - Vendor: 0x0000  Product 0x0000 Version 1.0
   Configuration: 1
   - Interfaces: 1 Self Powered 0mA
     Interface: 0
     - Alternate Setting 0, Endpoints: 1
     - Class Hub
     - Endpoint 1 In Interrupt MaxPacket 8 Interval 255ms

Marvell>> usb part

no USB devices available

i use it, mkfs -t ext4 -O ^64bit -L kernel /dev/sdc1 Do you have any advice?

I apologize for the inaccuracy of the interpreter. You wrote -

... can I use the official kernel?

You cannot use the OEM core Linksys and OpenWRT. You can use the kernel from Chadster.

I have a problem, uboot can not read usb part details as following:

Try to rerun the - usb reset command. After it is executed, do you have Storage Device in the line?

scanning bus 0 for devices... 2 USB Device(s) found
       scanning usb for storage devices... 1 Storage Device(s) found

It doesn't matter, no need to apologize, Yes,I run usb reset usb start have a Storage Device，As you wrote！

scanning bus 0 for devices... 2 USB Device(s) found
scanning usb for storage devices... 1 Storage Device(s) found

but run usb part no USB devices available Also, my uboot source is http://www.protechs-online.com/downloads/McDebian/u-boot-recovery/WRT1900ACv2_WRT1900ACS_uboot_v1.0.13.bin my rootfs choose is https://archlinuxarm.org/platforms/armv7/marvell/clearfog

You have formatted USB storage, recorded in its root kernel and rootfs, but you do not read the disc? We can assume only one thing is that there is some incompatibility of USB flash with the port eSata/USB2. Try using a different USB storage.

yes，I tried, I used USB Flash and USB HDD, respectively, but the problem is the above display, USB HDD on USB2.0 port using `USB RESET 'will hold 

scanning bus 0 for devices... 1 USB Device(s) found
       scanning usb for storage devices...

I suspect that USB 2.0 voltage is not enough USB HDD on USB3.0 can use usb reset but usb part no display information usb flash use usb reset no display also. I not have estat wire and I buy a one tomorrow.

ValCher1961 commented 5 years ago

I sometimes, for tests, use USB-HDD or USB-SSD 2.5" drives, and I have no problem with the power. For continuous operation, I use the eSATA cord with SSD Drive
