NTX hwconfig tutorial, updating values

DISCLAIMER, wrong usage of ntx_hwconfig can >> BRICK << your device.

That being said, this is a small tutorial on how to use ntx_hwconfig.
In the example I am updating the Boot Options to enable boot from external mmc/sd card.
Its just a random option I picked because it happens to be a good example.

1. Update HWconfig Device Node first, (this fixes: [WARNING]Config version too old)
This updates your device configuration to match the version of the ntx_hwconfig tool. Do not skip this step.

-s : file name is system device node (seeksize=524288) .
* devicenode = /dev/mmcblk0 (internal Multi Media/SD card)
* devicenode = /dev/mmcblk1 (external Multi Media/SD card)
-u : upgrade config format .


2. Get the BootOpt field value in human readable format

-s : file name is system device node (seeksize=524288) .
* devicenode = /dev/mmcblk0 (internal Multi Media/SD card)
* devicenode = /dev/mmcblk1 (external Multi Media/SD card)
-a [Action type] : [hwcfg(default)|cmd2|cmd_test]
* action type = hwcfg
* field value = BootOpt

Result Good: [47] BootOpt=ESD:OFF

Result Bad (goto step 1): [47] BootOpt='[+] 0x00'


3. Get the BootOpt field value (digital)

same as above only we want the digital field value
-d : force set/get field value as digital .

Result: [47] BootOpt=0x00


4. Set the BootOpt field value to 1 (digital)
same as above only we want to 'set' the digital field value
1 = the value we want to set
write = the action we want to perform
-f : force write hardware setting without protection .

Result: Hw config field "BootOpt" set as "1" success !!


5. Get the BootOpt value, to see if its updated.
Result: [47] BootOpt=0x01


6. Get the BootOpt field value in human readable format

Result: [47] BootOpt=ESD:ON


Enjoy
