OpenOCD烧写程序时报错Error:Device ID 8xle2g8a6d is not known as FESPI capable

Nuclei Studio 2023.10版中烧写程序时有报以下错误:

参见这个 https://github.com/riscv-mcu/hbird-sdk/issues/8

Info : Using libusb driver
Info : clock speed 1000 kHz
Info : JTAG tap: riscv.cpu tap/device found: 0x1e200a6d (mfg: 0x536 (Nuclei System Technology Co Ltd), part: 0xe200, ver: 0x1)

因为在openocd 2023.10中,将flash bank $_FLASHNAMEfespi修改为了nuspi,需要工程中的openocd配置文件中的fespi修改为了nuspi, 以蜂鸟工程为例,将hbird_sdk/SoC/hbirdv2/Board/mcu200t/openocd_hbirdv2.cfg修改为如下配置,工程即可正常使用。
