OOLITE -V3.2 | Unable to mount rootfs , mediatek board

Installing and Using OpenWrt
1

Hi,

I am trying to flash my OOLITE V3.2 based board which has 64MB RAM and 32 MB RAM,

The default ramdisk image is working fine in
tftp boot to SDRAM as well as tftp boot to flash.

I wish to flash the squashfs image to SPI-NOR Flash - GD25Q256CYIGR
I tried adding its support in spi-nor.c as well but i feel that image is not getting loaded in SPI Flash.

Any help in this would be very helping

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.

-You are booting from RAM.... loaded over tftp.
-You are then instructing the kernel ( non-openwrt? ) to find it's root filesystem in the cmdline option mtdparts.... which
-> a) your kernel is not honoring

Explain more about exactly what you did when you "tried adding its support in spi-nor.c".... including sources your working from, modifications done and how you expect to be able to flash assuming SPINor is fully functional.

Hi wulfy,

Thanks for your response,

I tried flashing on SPI Flash as well,
below are the logs for same:

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.


You choosed 2

2: System Load Linux Kernel then write to Flash via TFTP.

Please suggest where i am doing a mistake,

For making spi-nor.c changes, i followed this link,

https://patchwork.ozlabs.org/patch/793294/
and this is the code branch i am using,


Please note, if i create a ramdisk image from this branch, it works perfectly fine for oolite board.

Any help would be great

Thanks

Also,

These are the options i have,

How can i use spi command line to load image at a particular address in spi flash:

Environment size: 224/4092 bytes
MT7628 # help

?       - alias for 'help'
arb_erase - erase arbitraly position FLASH memory
bootm   - boot application image from memory
cp      - memory copy
erase   - erase SPI FLASH memory
ew      - erase_write parttition!
go      - start application at address 'addr'
gpio_in - Set gpio to input
gpio_r  - Read gpio status
gpio_w  - Set gpio out
help    - print online help
httpd   - Run httpd!
loadb   - load binary file over serial line (kermit mode)
mac_r   - read mac address!
mac_w   - write mac address!
md      - memory display
mdio   - Ralink PHY register R/W command !!
mm      - memory modify (auto-incrementing)
nm      - memory modify (constant address)
printenv- print environment variables
reset   - Perform RESET of the CPU
rf      - read/write rf register
saveenv - save environment variables to persistent storage
setenv  - set environment variables
sn_r    - read serial number!
sn_w    - write serial number!
spi     - spi command
tftpboot- boot image via network using TFTP protocol
version - print monitor version
write   - write file FLASH memory

And this is my current uboot printenv output:

MT7628 # printenv

bootcmd=tftp
bootdelay=3
baudrate=57600
ethaddr="00:AA:BB:CC:DD:10"
filesize=6af60a
fileaddr=80A00000
ipaddr=192.168.10.101
serverip=192.168.10.100
autostart=no
bootfile=firmware.bin
stdin=serial
stdout=serial
stderr=serial

Environment size: 224/4092 bytes

and these are the spi commands i have

MT7628 # help spi

spi spi usage:
  spi id
  spi sr read
  spi sr write <value>
  spi read <addr> <len>
  spi erase <offs> <len>
  spi write <offs> <hex_str_value>

I would be okay at this stage if i am able to flash it using spi commands as well.

Thanks

you are talking about the minibox 3.2?

using oolite code means you need to get help from oolite..(
gainstrong? )..

otherwise you have to start from here;
https://openwrt.org/toh/hwdata/gainstrong/gainstrong_minibox_v3.2

diving into spi write without firm reason is a recipe for trouble.
