The following bootloader works fine but I think the source code in the repo does not match the bootloader hex file. https://github.com/LGTMCU/Larduino_HSP/tree/master/hardware/LGT/avr/bootloaders/lgt8fx8p

Indeed.

Somehow the factory hex file wokes but none my build hex file work.

I use a Nano and follow the following instruction to build LGTISP which seems to work fine. https://github.com/dbuezas/lgt8fx/tree/master/lgt8f/libraries/LarduinoISP

I found a mistake in my build that frequency should be 16MHz. But it still does not work.

I will give up for now. Hopefully someone else who is more familiar with the chip can chime in and help out.

I have also build the hex file with Atmel toolchain based on avr-gcc 5.4.0 and 7.3.0, as well as MSYS2 avr-gcc 8.5.0, only the avr-gcc 5.4.0 based version works.

Here are the major changes by the vendor from an older version of optiboot (v5.0). There are also quite some changes if you compare the source codes. https://code.google.com/archive/p/optiboot/downloads https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/optiboot/optiboot-v5.0.zip

1) the header file is provided by the vendor here. https://github.com/LGTMCU/Larduino_HSP/blob/master/hardware/LGT/avr/bootloaders/lgt8fx8p/lgtx8p.h

2) initialization sequences https://github.com/LGTMCU/Larduino_HSP/blob/master/hardware/LGT/avr/bootloaders/lgt8fx8p/optiboot.c#L458-L468

  // WDT clock by 32KHz IRC
  PMCR = 0x80;
  PMCR = 0x93;

  // system clock: 16MHz system clock
  CLKPR = 0x80;
  CLKPR = 0x01;

  // enable 1KB E2PROM (for LGT8F328P)
  ECCR = 0x80;
  ECCR = 0x4C;

3) Makefile changes here. https://github.com/LGTMCU/Larduino_HSP/blob/master/hardware/LGT/avr/bootloaders/lgt8fx8p/Makefile#L336-L354

lgt8f328p_isp: isp

4) Watchdog related changes.

5) GUID

6) EEPROM related changes

BTW, even though 2KB EEPROM are reserved, the bootloader does not support EEPROM read/write.
