I’ve tried to radxa-zero-erase-emmc.bin file to erase eMMC then rz-udisk-loader.bin to load it for formatting
[using windows 11 + radxa zero 4gb ram and 6gb eMMC]
But the size is showing me 128MB instead of 64GB - I cant seem to see any other partition or unlocated partition under disk management.
I would appreciate if anyone has an idea what i might be doing wrong ? or if there is a way to wipe eMMC another way to resolve this issue?
Thank you
radxa-zero-erase-emmc.bin will expose eMMC as a storage device by itself. Try using this one only.
@RadxaYuntian
I did try using radxa-zero-erase-emmc.bin i get this output from RZ USB Boot Helper (windows 11)

But still have the size 128MB
I did install the driver again to see if anything will change
But no change
Same result it doesnt show 64gb
Yes I do have serial cable that i can use.
Then can you capture the log when you load radxa-zero-erase-emmc.bin?
Hi, @RadxaYuntian
I tried to connect via serial port, but i got some problems. Im wondering if there is a solution for it.
Im using : Windows 11
1) I did connect my USB to TTL cable as described in wiki
2) I did install Putty.
3) Entered necessary information
4) Checked Device Manager to see if all looks good, and there was a problem.
5) I downloaded the driver and installed from Prolific website
It did fix the problem with Device Manager, and it showed up;
but i can not connect via Putty and its giving me error
As a note; I noticed Prolific website had information about different part numbers and the number it showed up in my device manager has EOL on the website. Im not sure if this information helps but i wanted to share.
I appreciate the help, this is the first time im using USB to TTL and im not sure what else i can do to troubleshoot this issue.
Thank you
Well then you probably should trust your device when it was telling you the cable won’t work in Windows 11…Just because you force installed a driver (which will actually change the device name shown in Device Manager) doesn’t mean the issue goes away. FTDI cable is recommended.
Edit: here seems to be a workaround for it. I still recommend a new cable though.
can you give me a tip on what kind of cable ? i have no idea what to look for.
ok, im getting this one then. Looks like its a match for FT232RL ?
and i believe i can just use normal jumper cables with this ? or anything specific i need to know ?
Thank you
Looks like the jumper cable is included in the box. Don’t forget to switch the voltage switch jumper to 3.3v though.
Thank you for letting me know !!
My I suggest diskpart ? You get to this utility by pressing the windows key on the keyboard and typing diskpart
After maybe a prompt you get what looks like a DOS screen already running the diskpart utility
type list disk
you will see a list of all drives on the PC and their capacity
you need to identify all the storage devices: PC drive, USB key, SD card or eMMC in a cradle
Each storage device will have a number associated with it. 0 will be the PC hard drive and your flash device should be 1, 2, etc. Make sure you know which digit to use in the next command
type select disk 1
type clean
Read the display for any errors in the operation. Type exit.
Eject and reinsert the flash. You may have to format. Make sure the device is back to normal.
What happens when you make linux live usb devices and os installers is that you record large image and iso files onto the flash memory. Your program may be mkusb, rufus, yumi, imagewriter, win32diskimager, ubuntu USB writer or whatever. It may use the flash in ways your PC cannot read, or it may set fuses to change the device behaviour.
Diskpart is a utility that has been part of Msoft since forever. But be careful! It has no guardrails and you risk deleting your entire windows drive and bricking your machine.
I think diskpart and Disk Management uses the same API underneath. They should give the same result (except for some minor things like Microsoft Reserved Partition is hidden in DM but not in diskpart).
Hello again,
I got the USB > TTL device and connect it to my workstation. [3.3v]
Looks like Putty wasnt letting write in terminal, so i changed the settings to Force ON, and it does work probably.
But, when i run “radxa zero erase emmc.bin” Putty terminal doesnt show anything.
I did save the putty.log on my desktop but its just empty.
Is there another step / setup that i need to do to see the log ?
Thank you
i couldn’t take this path, because I’m working on my workstation, and I have some drives connected that puts it in to risk with my very little knowledge.
Thank you for explaining and for your suggestion.
