ch32v307 openocd

我用openocd下代码

Info : device id = 0x7b45b051

Info : flash size = 288kbytes

Info : ROM 192 kbytes RAM 128 kbytes

Info : Flash write discontinued at 0x00028778, next section at 0x00030000

Warn : no flash bank found for address 0x00048000

报错是为什么

您好,有可能是代码超出192K的范围了,可将FLASH、RAM的配置修改成288K+32K试一下。此外,麻烦说一下是调试还是命令行下载,完整的输出信息是啥,可以截图发出来看一下。

另外,我用了CH32的非零等待区,所以代码是比192K大的,如果用MRS是可以下载的


而且我注意到他报回来的log显示

Info : flash size = 288kbytes

Info : ROM 192 kbytes RAM 128 kbytes

Info : Flash write discontinued at 0x000284e0, next section at 0x00030000

Warn : no flash bank found for address 0x00048000


我有两个问题:

1. Info : Flash write discontinued at 0x000284e0, next section at 0x00030000这句是在说什么意思,为什么flash写入没有继续

2. 0x00048000是288kbytes,但是我整个配置都没有288kbytes,这个288kbytes是从哪蹦出来的
