根据官网提示按键REC进入烧录模式

TB-RV1126D: 按住开发板REC按键后,Type-C线连接主机端的USB Host接口和开发板的DP In接口,大约1秒后松开按键。

发现进的是Loader 烧录模式, 烧录之后,再使用REC按键无法进入Loader烧录模式, maskrom按键也无法进入,RST按键可正常复位。

查看图纸()发现maskrom按键只是将FLASH_D0/EMMC_D0 对地短路。

 

 

 

 

网上有用户研究发现需要短路maskrom 按键旁边的电容和电阻(将EMMC clk对GND短路)方可进入maskrom。

经过试验此方法确实可行。

 

 

为方便后续调试,需要将maskrom按键飞线将EMMC_CLK对地短路。

 修改后如下图

 

 

长按左上角maskrom按键后再上电或重启,板子即可进入maskrom烧录模式、
