larduinoisp's Issues

can be used this programmer with LGT8F328P ( note the P at the end )

I tried to program WAwgat nano v3 without success ...

It seems that it only works with LGT8F328D (note the D at the end).
The hardware programmer SWDICE_mkii pro is supposed to program both MCUs.

Is there any way to use this program with the LGT8F328P MCU?

Thanks.

SWD debug ISP protocol datasheet ? SWD双线调试/量产接口 ?

Hello there !

Could you share the datasheet for the SWD debug ISP protocol, please ?

datasheet for SWD双线调试/量产接口, please ?

Can burn .hex with Arduino Nano

I have sucessfully flashed a small blink (without bootloader) program using a LGT8f328p to flash another LGT8f328p using the specs and the wiring the instructions said to do.

But I could not flash using an Arduino Nano for that, repeating the same wiring and specs I used with the LGT8f328p flasher.

I am a bit worried because I have only one LGT8f328p with me, the another one I used I picked with a friend of mine who had gently lent me but I have sent It him back.

The sketch in the repo is supposed to work in an Arduino Nano, right? Or I can only be used with a LGT8f328p acting as a flasher?

I have also selected the Arduino IDE to flash my Arduino Nano as a LGT8f328p, with the RX_SERIAL_BUFFER_SIZE set to 250, but It didn't succeed either.

The avrdude command I am using is:

avrdude -u -c stk500v1 -p m328p -P /dev/ttyUSB0 -b 19200 -B 1.5 -U flash:w:"/path_to_hex_file"

*using the LGT8f328p flasher I only replace the /dev/ttyUSB0 for /dev/ttyACM0

and It's not working only with the Arduino Nano.

LGT8F Lock Bits

Hi
Can this ISP write the lock bits in LGT8F? Do the LGT read out protection work like the original ATMega?
