Oopsie.. LiteVNA64 flashing

[hvegh]

So I figured my luck with the updated firmware using branch and TARGET=F303:

Put the device in DFU mode by pulling BOOT0 HIGH and flashed the H4 image, see update procedure below.
Screen stays dark..

Any ideas maybe how to fix?

Found DFU: [2e3c:df11] ver=0200, devnum=32, cfg=1, intf=0, path="2-2", alt=1, name="@Option Byte   /0x1FFFF800/01*048 e", serial="AT32"
Found DFU: [2e3c:df11] ver=0200, devnum=32, cfg=1, intf=0, path="2-2", alt=0, name="@Internal Flash  /0x08000000/ 512*2Kg", serial="AT32"

So i went and went ahead and flashed :

~# dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D build/H4.bin
dfu-util 0.11

This source and firmware only for H or H4 hardware.
LiteVNA use different code (but at this moment most hardware independent part equal, i port this code here) and not open source.

You need install LiteVNA64 firmware
https://www.zeenko.tech/litevna
Or use my build

I open this thread. As i can see you erase LiteVNA bootloader (not shure, as i know AT32 CPU not allow flash from STM32 DFU util)
Suggest go to this thread
https://groups.io/g/nanovna-beta-test/message/4224
Try help restore your device

Will check it, thank you!

[DiSlord]

Here is instuction how restore LiteVNA after full brick (restore bootloader and firmware)

[hvegh]

Ah yes!

I have restored an initial firmware backup using:
dfu-util -d 0483:df11 -a 0 -s 0x08004000:leave -D ../archive/VNA_v1.2.bin

The AT32 microconroller needs extra 0x4000 offset...

Solved!
