Howdy!

Just experiment with the ch552 this morning ...

I can see WinChipHead ...

Got this error, when I attempted to flash ...

rasyoung@vic2016:~/code_test/8051/wch/ch554_sdcc/examples/blink$ sudo python ch55xtool.py --file blink.hex Found CH554. BTVER: V2.31.

I notice in the hex file ... the first lines are "short"

It reports the correct chip type and bootloader version. Wondered if you know what was the issue?

Thanks for posting this code!

Are you sure this can be used to program an Intel HEX file? It mentions bin in the readme... (Actually, I'm also having a different problem with this tool, where it says it's programmed but the chip isn't happy afterwards. I've used this same code on chips with earlier bootloaders without a problem, so I'm inclined to think that it's this tool doing something, but I'm not sure what, yet... I found this while I was looking to see if it was expecting a .hex file)

ishiyakazuo commented 4 years ago

Just a quick update -- I was able to get it to work with a binary file in my case, but not hex. (It could've been my hex file, but I think the answer is that flashing a bin file is the "safe" solution for now.) I didn't have a CH554 on hand (nor CH552) with bootloader 2.3.1 -- I used CH551. It didn't work immediately with CH551, but I patched it to fix the issue I was running into. If you try a bin file and it still doesn't work, you might want to try my fork and see if that resolves it. I can't say for sure that my workaround doesn't break anything other than CH551 and CH552.

This does not working with hex, I might gonna to add it （and check file name suffix）later

hmmm... I dont have older CH55x on my hand :( , so if @ishiyakazuo test it works, that will be nice.

I have some CH55x with bootloader 2.3.1 still, if this is needed.
