Rigol DHO800/900 new firmware... 1.03

[sandor626]

I read your forum only after updating the firmware (and noticing some malfunctions)

[ptluis]

you can easily brick your device!

Technically not a "brick", it still boots, other apps work, just not the 'scope app.

What firmware version "bricked" your scope? v00.01.03.00.04 or v00.01.03.00.06?
I'm still able to download v00.01.03.00.06 from supportint.rigol.com

Can somebody share v00.01.03.00.06 ? Looks like its not available on a Rigol page - link goes into error page 

Even maybe other v00.01.03 for a better hacking

Changes in relation to the v00.01.02.00.02, at first glance:

• FPGA firmware.
• New module fan_gpio_clt.ko - likely after decompilation, we will be able to manage fan voltage as we want. Eventually this can only turn on and off the fan. But there is a trace from a deleted PWM kernel module (both versions).
• New script quick_boot_test.sh - pseudo sleep mode - FPGA, fan and screen backlight is shut down, but CPU is still running (In my tests I was able to run this scope on Debian GNU/Linux and without fan for many hours). Maybe they don't know how to do a S3 mode or Android 7.x is not able to handle it.
• Some strange and top secret staff hidden in a /tools/spidev and "golden_ver" variables in a quick_boot_test.sh.
• All apk files was changed (Launcher.apk, Sparrow.apk, Webcontrol.apk).

Now I think to change only FPGA firmware on my scope and see what will go boom

I did it. After small basic tests I don't see any changes in scope behavior or measurements. Bug in a bode plot is not fixed after this change.

I copied (by overwrite) /rigol/FPGA/BOOT.bin and /rigol/FPGA/BOOT_SelfTest.bin by command adb push.

FPGA was reflashed with command:

Code: [Select]

/rigol/shell/reload_fpga.sh /rigol/FPGA/BOOT.bin 0x400000

After copying new files from 1.03 (/rigol/tools/spidev, /rigol/drivers/fan_gpio_clt.ko and /rigol/shell/quick_boot_test.sh), making them executable (chmod +x path/to/a/file) and with little changes in a quick_boot_test.sh I managed to make a fully working "pseudo-sleep" in a 1.02, but only via adb:

Argument "on" takes around 30 seconds - at least for now.

After "off", network still works and all apps (in exception of a scope app) can be used via http://your.crappy.scope.ip/control.html

Now I will try to make a "game mode" without fan, but most likely I need to make a binary changes in a fan_gpio_clt.ko to make a screen work (backlight/brightness doesn't do the trick).

My modification of a quick_boot_test.sh is in the attachment. Bon apetit!

Now I will try to make a "game mode" without fan, but most likely I need to make a binary changes in a fan_gpio_clt.ko to make a screen work (backlight/brightness doesn't do the trick).

I decompiled this module and only one thing it do is turning on and off single GPIO pin. Looks like fan and a backlight are powered from this pin, so for now it will be impossible to turn off the fan and have internal screen visible.

Anyway, I did a game mode in this script - new version is in the attachment.

----------------------------

Make this to go into pseudo-sleep:

Code: [Select]

/rigol/shell/quick_boot_test.sh off
Turn it back on:

Code: [Select]

/rigol/shell/quick_boot_test.sh on
Game mode (scope app disabled and it will not work when loaded by hand). To use scope app, use argument "on", as above.

Code: [Select]

/rigol/shell/quick_boot_test.sh letsplay
---------

Modes can be switched at any time, no matter what mode was before.

Physical power switch most likely will turn it off completely - maybe upgrading Launcher up to 1.03 will help? I will try it tomorrow, because Im tired.
