One thing I found in researching PVI is that it is part of an old Taiwan paper company called The Yuen Fong Yu Group, that started ops in 1935 during the Japanese occupation of Taiwan island (1895-1945). The founders were Taiwanese and the owners still are. Yuen Fong Yu means "Forever Wealth Remnants" in a loose translation of the three Mandarin words, and the company name might mean something like "Remnants of Infinite Prosperity." E-Ink will be in good hands in Taiwan, and PVI looks poised to hit the bigtime globally, since 90 percent of all e-readers use the E-Ink technology. The parent company used to make toilet paper, and still does I believe. If you google the parent name "Yuen Fong Yu Group" you can see their website in English and Chinese.

Add stripped down .config to busybox directory from NiMa/TuxLinux
Save this below as .config in the root of the busybox directory.
make menuconfig
Note: This is already set in the .config above but run menuconfig anyways and exit save so you don’t get all these y/n questions depending on the busybox version you are using. It will fix these for you doing that.
Under Settings enable with an asterisk (spacebar):
[*] Build static binary (no shared libs) (NEW)
Fix Sync Error
sync.c:(.text.sync_main+0x5c): undefined reference to syncfs
man syncfs
VERSIONS
syncfs() first appeared in Linux 2.6.39; library support was added to glibc in version 2.14.
config FEATURE_SYNC_FANCY [=n] (Don’t disable actual sync just the fancy option under it)
Under Coreutils => Sync => Remove the asterisk (Spacebar) =>
[ ] Enable -d and -f flags (requires syncfs(2) in libc)
Exit Exit Save Yes
Fix DADFAILED Error
Note: Fixed in newer versions but if not.
networking/libiproute/ipaddress.c:345: error: 'IFA_F_DADFAILED' undeclared (first use in this function)
vi ~/code/busybox/networking/libiproute/ipaddress.c
Find DADFAILED around line 345
if (ifa_flags & IFA_F_DADFAILED) {
ifa_flags &= ~IFA_F_DADFAILED;

}
Change to:
#ifdef IFA_F_DADFAILED
if (ifa_flags & IFA_F_DADFAILED) {
ifa_flags &= ~IFA_F_DADFAILED;
printf("dadfailed ");
}
#endif
Make Busybox Install

--------------------------------------------------
You will probably need to make your busybox binary
setuid root to ensure all configured applets will
work properly.
--------------------------------------------------
If busybox needs to be smaller to fit in the same DD space the prior kernel used (2.2MB) use the UPX tool.

Boot the Stock SDCard Image then grab platform-tools and connect to ADB Shell
https://developer.android.com/studio/releases/platform-tools#downloads
With the device connected via USB run:
adb shell
At the prompt # check out the permissions of /dev/ttymxc4
ls -l /dev/ttymxc4 crw------- root root 207, 20 2010-01-01 02:00 ttymxc4
Copy the 207 20 to the ttymxc4 mknod value below.
Note: Do not put / in front of your dev folders on the following mknod commands or you will create them in your systems dev folder instead of the busybox/_install/dev/ folder.
cd ~/code/busybox/_install mkdir dev sudo mknod dev/console c 5 1 sudo mknod dev/null c 1 3 sudo mknod dev/ttymxc4 c 207 20

Two Methods to Alter Device U-Boot ENV
Hardware UART Way
Take the device apart and connect the USB to 3.3V TTL Adapter to GND TX RX
USB to UART Adapter
Cheap Adapter 3.3/5V (Sony PRS-T1 UART is 3.3V)
https://www.aliexpress.c o m/item/32273550144.html
Expansive Adapter (Multiple voltages to hack even more devices not just the Sony)
https://www.aliexpress.c o m/item/1005003309224312.html
Connect With Putty (Windows)
Serial COM4 115200
Connect With Minicom (Linux)
minicom -D /dev/ttyUSB0
CTRL + A then Z
Then O (cOnfigure Minicom..O)
[Configuration]
Serial port setup A - Serial Device : /dev/ttyUSB0 E - Bps/Par/Bits : 115200 8N1 F - Hardware Flow Control : No Modem and dialing (Clear all these settings) A - Init string .........

Note: There is an external watchdog running that will reset the device every 30 seconds. Which makes it difficult to type commands in the console. Copy and paste the values to the terminal to get the job done.
MX50_ARM2 U-Boot > printenv
Backup what it spits out to a txt file.
Change the env.
This is to boot from the SDCard image.
setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext4 rw rootwait init=/linuxrc console=ttymxc4,115200 bootdev=0 rawtable=0xF40000

Environment size: 387/131068 bytes
Note: You can use the stock build with adb shell as in the image it has the adb driver running.
sudo apt install adb adb shell #
To boot recovery from SD card
setenv bootargs 'root=/dev/mmcblk0p1 rootfstype=ext4 rw rootwait init=/linuxrc console=ttymxc4,115200 bootdev=2 rawtable=0xF40000'
To boot normal system from SD card
setenv bootargs 'console=ttymxc4,115200 init=/init bootdev=0 rawtable=0xF40000'
Change this to boot the customized kernel:
setenv bootargs ‘root=/dev/mmcblk0p1 rootfstype=ext4 rw rootwait rdinit=/linuxrc console=ttymxc4,115200 bootdev=0 rawtable=0xF40000’
setenv bootcmd mmc read 0 ${loadaddr} 0x800 0x1400\;mmc read 0 ${loadaddr_ramdisk} 0x2800 0x258\;bootm
saveenv
The device should now boot from the SDCard slot instead of the eMMC.
Recovery Mode Boot Way
Copy the uboot env from this image to a separate file:
dd if=~/code/sd_card_PRS-T1_1.0.07_adb_enabled.bin skip=786432 of=uboot_new.bin bs=1 count=131072
wget https://projects.mobileread.com/reader/users/porkupan/rupor/Releases/rescue/20121208/rupor-rescue.7z 7za e rupor-rescue.7z
Copy uboot_new.bin to Rupor Rescue SD Card, along with the other files that are already there…
SD Card Layout
OS Firmware |-files | |-update.img uboot_new.bin
Boot Rupor Rescue (Hold HOME + MENU during power on)
Remount SD Card as writable.
mount -o remount,rw /dev/mmcblk0p1 /initrd/mnt/sd
Change directory to the SD Card mounted.
cd /initrd/mnt/sd
Backup the old uboot env to a file.
dd if=/dev/mmcblk2 skip=786432 of=uboot_old.bin bs=1 count=131072
Write a new one.
dd if=uboot_new.bin of=/dev/mmcblk2 seek=786432 bs=1 count=131072
Reset device and it should now be booting to the SD Card image.
After that it should boot (in normal mode) from the SD card that has my image on it. Rescue mode should still work as before, as this only changes the "active uboot env" instead of "rescue uboot env".

Doc: WM8321G Address R16388(4004h) Watchdog, Bit 14 WDOG_DEBUG, Default 0, Watchdog Pause 0=Disable 1=Enabled (halts the watchdog timer for system debugging) Protected by user key
This would show if you can't modify the watchdog bit without the code i2c dev 0 i2c probe i2c md.w 0x34 0x4008 -> default value is 0x0000
We have to write a magic value 0x9716 to this register, to allow writes to WDOG_DEBUG etc. MX50_ARM2 U-Boot > i2c mm.w 0x34 0x4008 0x9716
Print out the bit set for 4004 MX50_ARM2 U-Boot > i2c md.w 0x34 0x4004
Then you should be abled to activate the watchdog debug mode MX50_ARM2 U-Boot > i2c mm.w 0x34 0x4004 (change bit 14 of whatever you get from above to 1)

If this table says:

Hex to Decimal

How do you compute these values of dd to the above?
dd if=/dev/mmcblk2 of=/initrd/mnt/sd/WF_OLD.img skip=17408 count=2048 bs=1024 sync dd if=/dev/mmcblk2 of=/initrd/mnt/sd/Vcom_OLD.img skip=15876 count=1 bs=1024 sync
Waveform to Decimal: 17825792Bytes : 2097152Bytes skip=17408Blocks. Skip 17408 ibs-sized blocks at start of input bs=1024Bytes. Read and write up to BYTES bytes at a time (default: 512);overrides ibs and obs count=2048Blocks. Copy only 2048 input blocks Starting Point of DD Copy 17408Blocks * 1024Bytes = 17825792Bytes ☑️ Count 2048Blocks * 1024Bytes = 2097152Bytes 17825792Bytes + 2097152Bytes = 19922944Bytes ☑️ Next Data Point LOG :19922944 ☑️:5242880
The second number is how many bytes added to the starting point
So now we can see where VCOM is ripped from
dd if=/dev/mmcblk2 of=/initrd/mnt/sd/Vcom_OLD.img skip=15876 count=1 bs=1024
skip=15876 count=1 bs=1024 VCOM Start: 15876 * 1024 = 16257024 1*1024 = 1024 VCOM End: 16257024 + 1024 = 16258048
Id :0x00f80000:0x00020000 Id :16252928:131072
Therefore VCOM is inside Id of the 26MB Raw Data Area
