28075 CCS6无法烧写程序,提示错误如下:C28xx_CPU1: Error during Flash programming (Flash algorithm returned error code). Operation cancelled

DSP为28075,采用uniflash可以烧写程序并正常运行,但是使用CCS环境烧写程序提示错误如下:

C28xx_CPU1: Error during Flash programming (Flash algorithm returned error code). Operation cancelled.
C28xx_CPU1: File Loader: Memory write failed: Unknown error
C28xx_CPU1: GEL: File: D:\code\TBM180\TBM180_11KTI\Debug_flash\TBM180_11KTI.out: Load failed.
C28xx_CPU1: Error during Flash programming (Flash algorithm returned error code). Operation cancelled.
C28xx_CPU1: Please make sure the memory location you are programming have not already been programmed.

请问题是哪里的问题,是芯片背面大焊盘(GND)焊接不良吗?

Young Hu:PowerPAD需要焊接,CCS升级到最新版本

多谢回复!
这个批量产品问题, 我们之前已经用了上万片,没有问题,这次PCB升级了,原理图没有更改,出现了这个问题,现在推测是PowerPAD焊接不良,但是用uniflash可以烧写,也可以正常运行,更换CCS版本也能解决这个问题,我的问题点是:这个问题的根本原因是否是PowerPAD焊接不良,担心产品批量出问题。
