arduino通过预先写入的bootloader,每次通过串口给arduino板下载程序时,首先会令arduino板复位一次,这样就先进入了bootloader,接着向arduino板发送特定的下载指令,bootloader识别到这些指令后就会紧接着开始接收剩下的新的程序代码写入到内部flash中,如果没有进行下载,bootloader没有识别到下载指令,那么它就会跳转到程序区正常...
BOD(Brown out detection)因为使用的是3.3V工作电压,所以设置成2.7V低电压保护。Bootloader可以选择不使用,这样每次都需要烧写板进行程序烧写,但我选的是使用UART0口,主要还是考虑后续可以直接用Arduino Pro Mini板连接电脑下载程序。晶振使用的是3.3V外源8MHz。Variant应设置成328PB,这很重要,必须要根板子上的芯片型...

An Arduino core for the ATmega328, ATmega168, ATmega88, ATmega48 and ATmega8, all running theUrbootbootloader. This core requires at least Arduino IDE v1.8, where v1.8.9 or newer is recommended. IDE 2.x should also work. From MiniCore version 3 and onwards, the Optiboot bootloader has ...
bootloader烧录的是哪个,在串口烧录时,需要选择对应的串口,有些bootloader是支持串口0或者串口1烧录程序的。或者直接使用你烧录bootloader的烧录方式进行程序烧写测试一下。另外需要注意的是,熔丝位烧写一定要和你板子的供电电压以及外部晶振匹配。如果bootloader和烧写的熔丝位参数对不上,也会出现这个情况。 2024-07-30 23...

“Upload Using Programmer” The Arduino IDE provides the ability to upload a sketch to a board using AVR in-system programming (with a programmer connected to the 2×3 ISP header). This is done by running theUpload Using Programmercommand in theSketchmenu. Before running that command, you mu...
I suspect that PlatformIO is passing the argument “-cstk500v2” to AVRDUDE. That would be the right argument to use if you are using the ISP interface, but if you are talking to the serial bootloader on the A-Star 328PB, that argument needs to be “-carduino”. ...
