TMS320C6678EVM fpga烧写

Other Parts Discussed in Thread: UCD9222

大家好!

我在看EVM的文档时,发现开发板上,6678的bootmode信息是由fpga通过spi提供的,由fpga强制开发板启动到I2C的IBL,我现在想让6678直接启动到SPI上的自己写的一个二级引导程序上去,而不要E2PROM这些,因此想修改FPGA程序,看到文档中提到,在电源模块工作时是无法直接修改FPGA的,另一种方法是在CCS中通过6678去更新FPGA,也有网友提到了这种方式,但是找不到相应的工具和例程,希望TI的工程师能够提供一下,谢谢。

2.6 The FPGA code update issue on the EVMs

 

The FPGA cannot be reprogrammed while the UCD9222 contains a configuration and it is operating. One solution requires erasing the configuration from the UCD9222 before programming the FPGA. The alternate and preferred solution is reprogramming the FPGA from the DSP with CCS connected. A utility to perform this is available.
