DSP28335的FLASH无法擦除和编程

请您看一下我之前的回复，是和您基本相同的问题

e2echina.ti.com/.../587581

但是我CSM_PWL区并没有填写数据，显示的全是是unused

我在使用UNIflash擦除FLASHA的时候，提示是这个Error executing current operation. Please check the console for additional error information.

请您使用uniflash来试一下是否可以成功识别板子烧写程序。
另外请您使用uniflash从密码位置读取数据。0x33 FFF8-0x33 FFFF这些位置为多少？

能给出uniflash的全部错误截图吗？

这是使用Uniflash给DSP烧写程序的错误

下面是读取memory的错误

这是ERASE FLASHA的错误

这个是unlock的错误

不好意思，这回读取出来了，0x33 FFF8-0x33 FFFF这些位置的数据都是0，log提示如下C28xx: GEL Output: ADC Calibration not complete, check if device is unlocked and recalibrate.

unlock的时候提示如下
[2020/10/21 上午11:28:02] [INFO] C28xx: Starting device unlocking...
[2020/10/21 上午11:28:02] [INFO] C28xx: Device unlocked. To clear the programmed password, please erase Sector A of Flash memory.

以下是擦除FLASHA的错误log
[2020/10/21 上午11:28:27] [ERROR] C28xx: Flash Programmer: Error erasing flash memory. Device is locked or not connected. Operation cancelled

l烧写的时候提示如下
[2020/10/21 上午11:29:13] [ERROR] C28xx: File Loader: Verification failed: Values at address 0x00000@Program do not match Please verify target memory and memory map.

您好，我现在在工程里面加载了一个gel文件，然后解决了这些问题，请问gel文件的作用是什么呢。我之前的工程文件都没有加载过gel文件
