MSP430G2230: UpgradeUpgradeUpgradeUpgradeupUpgrade program via I2C

HI 

On MSP430G2230，We hope to upgrade the program through I2C；

Is there a feasible solution? Is there a reference code?

Thank you

Susan Yang：

您可以看一下

This application report describes the implementation of a bootloader that resides in the main memory of MSP430 flash-based microcontrollers (MCUs) using either Inter-Integrated Circuit (I2C), universal asynchronous receiver/transmitter (UART), or a serial peripheral interface (SPI) bus and CC110x RF transceivers to accomplish over-the-air download (OAD).

In the document "MSPBoot-Main Memory Bootloader for MSP430 Flash Microcontrollers", chapter 2.2.1.1 Force Bootloader Mode mentions the need to pull down "P1.3 in MSP430G2xxx" to control the bootloader mode;But I don’t see P1.3 from the datasheet of MSP430G2230. Does it matter? Which pin should I use to enter Bootloader Mode on MSP430G2230?

麻烦您再帮我确认下，我的同事在英文论坛也提了相同的问题，但得到的回复说MSP430G2230没有bootloader，需要自己实现；

问题链接如下，谢谢

我看了下，该芯片确实是不支持的
