AM3359: ICE_AM3359 v2开发板使用SD卡启动后无法connect target进行调试的问题

Part Number: AM3359

板子的型号是ICE_AM3359 v2,通过德州仪器 XDS100V2 USB 调试探头连接线连接主机和板子。主机环境是Ubuntu18.04+CCS10,交叉编译环境已经配置好了。

根据https://software-dl.ti.com/processor-sdk-linux/esd/docs/07_03_00_005/linux/Overview/Processor_SDK_Linux_create_SD_card_script.html中的步骤制作了SD卡,然后擦除了SPI flash,将J5的pin2和pin3相连。上电后能够启动SD卡里面的RTLinux系统。

接下来在Ubuntu18中打开CCS10,右键点击ccxml,点击Lanuch Selected Configuration,右键点击下拉列表中的Texas Instruments XDS100V2 USB debug probe_0/CortxA8,点击connect target。

过一会儿报错如下所示:

Error connecting to the target:
(Error -1170 @ 0x0)
Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.4.0.00129)

1、请教一下这个错误是什么原因引起的?

2、ICE_AM3359 v2怎样通过NOR启动?

3、制作好SD卡之后,如何将SD卡中的RTLinux操作系统烧写到板子上的存储里面?
