Amiko Alien2 Enigma2 BOOT problem

amiko bootAfter Amiko Alien2 bought, I tried to install AR-P image of Enigma2/PLI. But unfortunaly there was a problem with flash IC and bootloader.

 I able to boot only SPARK image, and even if I choose boot from enigma [ENIG] that i wrote to flash - tuner can't boot to it.

Symptomes:

The message that I see after I choose "Boot To E2" in "Reset To Factory Defaults" menu saying this:

Board: STx7105-PDK  [32-bit mode]

So, before I set "Boot To E2", the bootloader's environment variables area (0x0a0000...0x0c0000) was totally clean, and now it have env data, but bootloader ignoring it, and fails.

After studying U-Boot sources I found that Amiko's manufacture changed Flash-IC, It was at the 2nd-time, since they started selling that device!

Here is list of SPI-flash chips, used in this tuner:

  • Spansion S25FL016K (2MB) with JEDEC ID: 0xEF4015 (This flash chip is originally supported by U-Boot)
  • Atmel AT25DF161 (2MB) with JEDEC ID: 0x1F4602 (This flash chip support added in U-Boot of AMIKO_ALIEN2_1.2.51_E2_Boot_Upgrade.rar firmware)
  • Spansion S25FL016A (2MB) with JEDEC ID: 0x010214 (This flash chip is not supported by U-Boot)

So my tuner have last IC and it's not supported by any U-Boot versions, provided by vendor. Just imagine one last letter do whole trick: S25FL016K vs S25FL016A

 

So, if you are seeing exactly this message in console:

SPI:  ERROR: Unknown SPI Device detected, devid = 0x01, 0x02, 0x14 

Then you are have SPI-flash that does not supported by U-Boot.

WARNING: if you see different numbers on devid, DO NOT FOLLOW THIS GUIDE, you will brick it!

To add support for this chip, patched version of U-Boot is needed, here is changes t:

At the link below, you can download patched version of U-Boot (original Spark 1.2.54 U-Boot used as source):

alien2.u-boot.S25FL016A.bin.zip

 

 

Solution Guide:

To flash this U-Boot to your tuner:

  1. Download and unzip that file to the root directory of the flash drive.
  2. Run spark, if your tuner is not able to run it, force running by setting this commands in console:
    setenv bootargs "console=ttyAS1,115200 rw ramdisk_size=6144 root=/dev/ram0 init=/linuxrc nwhwconf=device:eth0,hwaddr:00:80:E1:12:40:69 ip=192.168.0.69:192.168.3.119:192.168.3.1:255.255.0.0:Spark:eth0:off stmmaceth=msglvl:0,phyaddr:1,watchdog:5000 bigphysarea=7000"
    nboot.i 0x80000000 0 0x00100000 ;bootm 0x80000000

    After this commands, spark must boot...

  3. After Spark booted, insert USB-flash frive to the back USB-port of tuner.
  4. Connect tuner to network and configure it.
  5. Run Putty/telnet on the host PC, and get access to the tuner.
  6. make sure you have u-boot on USB-flash drive:
    ls -la /storage/c/u-boot.S25FL016A.bin

    The output of this command must be like this:

    -rwxr-xr-x    1 root     root       1048576 Oct 12  2013 /storage/c/u-boot.S25FL016A.bin
  7. insert i2s.ko module:
    insmod /root/spark/modules/i2s.ko
  8. Burn flash with new U-Boot:
    flash_eraseall /dev/mtd7; flashcp -v /storage/c/u-boot.S25FL016A.bin /dev/mtd7; sync
  9. Reboot the tuner:
    reboot

 

 

Results:

 

After flashing new bootloader, You will see that spi-flash detected correctly:

The message

*** Warning - bad CRC, using default environment

means that environment partition - is clean yet.

 

 

Booting to Enigma:

 

So let's try to set boot from enigma now:

  1. Turn off tuner
  2. push [OK] and keep pushed
  3. Turn on tuner, you'l have to see [FORC] on display.
  4. release [OK] button
  5. push [DOWN], you'll have to see [ENIG]
  6. push [OK] and release (the tuner successfuly sets env variables, and boot to enigma)

The sample of successful setting of enigma-related environment variables:

3. RS232 Upgrade u-boot(left key)
4. Force into factory mode(right key)
Input Select:
set bootargs to bootargs_enigma2
..
SUCC

Congratulations, now your U-Boot understands environment variables, and there is no more "bad CRC" warnings related to environment vars.

Thanks for sharing! Do you

Thanks for sharing!

Do you know what I can do if with this error: SPI: ERROR: Unknown SPI Device detected, devid = 0x1f, 0x46, 0x02 ?

Happen after trying those command in effort to fix Alien2 stuck on boot:

PDK7105> set bootargs console=ttyAS0,115200 rw ramdisk_size=6144 init=/linuxrc root=/dev/ram0 nwhwconf=device:eth0,hwaddr:00:06:37:04:15:00 ip=192.168.40.83:192.168.40.19:192.168.40.1:255.255.0.0:lh:eth0:off stmmaceth=msglvl:0,phyaddr:1,watchdog:5000 bigphysarea=6000
