I need someone who can test a flash tool I'm working on, it's able to backup and restore the whole flash from FEL (Bootloader) mode.
It's important to understand it's in testing stage and you might need to recover it using an external spi programmer.
I managed to lock my flash twice by sending corrupted data, platform-tools didn't work anymore, had to remove the flash and erase it using a CH341A to make it work again.
It didn't happen again since I fixed the code, but I must give a serious, proceed-at-your-own-risk warning!
I'm doing my lasts tests, if it keeps working everytime without any issues, I'll release the tool for the brave.
It's not really required, as platform-tools + Backup Builder will do the job, but it's always nice to have a complete 1:1 backup.
Reading takes 50 minutes and writing 25.
Morgan, all it takes is installing and testing, don't be lazy, just try and check yourself and report the result
The worst that could happen is having to remove it and install the older version.
I extracted the scpi commands long time ago here

It's not wrong, this tool includes the ECC area, that's why the final size is 132MB, and only a backup of that size will be allowed when writing.
You can get the same reading with the CH341 selecting "Read OOB area".
Check NeoProgrammer.
It's also uploaded in the Drive folder (Hacking/CH341...)
Yes, my bad. Spare area, OOB(Out Of Band) area, ECC area...it's the same thing.
That area is reserved for ECC when enabled, or can be used as regular storage when disabled.
Anyways, remember it's a writable filesystem, two backups will probably be different if the scope was started between them.
The system will execute the file overclock/oc_manager from the usb drive. If there's no drive, overclock won't be applied.
Now you can try rising the CPU_OC_PLL_N multiplier in that file, rebooting each time to apply the new settings.
# Effective frequency is (BASE_FREQ*(N+1)*(K+1))/(M+1)
# Possible values:
# PLL_N: 1-31
# PLL_K: 0-3
# PLL_M: 0-3
# ------ USER ADJUSTABLE ------
# This example: (24*(26+1)*(0+1))/(0+1) = 648MHz
CPU_OC_PLL_N=26
CPU_OC_PLL_K=0
CPU_OC_PLL_M=0
# This example: (24*(13+1)*(0+1))/(0+1) = 336MHz (168MHz DDR)
MEM_OC_PLL_N=13
MEM_OC_PLL_K=0
MEM_OC_PLL_M=0
Don't buy this crap. Seriously.
I've trying to follow 50MHz signal pulses lasting 50-100us.
Larger Time division than 10-5us shows nothing or garbage.
In the zoom view, you can't scroll through the whole screen, so another useless feature.
SPI decoding keeps failing. No *** way to decode anything.
*** Hantek designers. Never again. Not even free, damn.
This scope is just crap.
It was a quite good offer at the release price, around $200, but now people seems to get it for almost $400!
What can I recommend having a 2D15 myself? All I can say is get anything but Hantek!
I'd make a new thread asking for options given a price tag, for sure you'll get a lot of nice feedback from experienced people.
