CC3551E: CC3551E APP_MCU Debug Connection Error -614

KuoWei Chen — Sun, 01 Nov 2026 15:47:22 GMT

Part Number: CC3551E
Other Parts Discussed in Thread: LP-EM-CC35X1, LP-XDS110ET

Hello TI Support,

We are experiencing a debug connection issue with a newly purchased CC3551E evaluation board.

Hardware:

LP-EM-CC35X1 Rev A
LP-XDS110ET Rev B

Software:

Code Composer Studio 21.0.1
SimpleLink Wi-Fi SDK 10.20.00.39
SimpleLink Wi-Fi Toolbox 4.3.23

Problem:

The firmware builds successfully, and the XDS110 SWD integrity test passes. However, CCS fails to establish a debug connection to APP_MCU with the following error:

Error -614 (3:16:1): The target indicates there is an error condition from a previous SWD request.

The board was received without any known prior activation or security configuration.

Questions:

What are the likely causes of Error -614 on CC3551E?
Does a new CC3551E evaluation board require initial security configuration before debugging?
How can we verify the device state without modifying its security settings?
Are our CCS, SDK, and Toolbox versions compatible?

We would appreciate guidance on non-destructive diagnostics before making any irreversible device configuration changes.

Thank you.

PSPICE-FOR-TI: PSPICE-FOR-TI: PSpice for TI installation fails: unable to resolve pcb.cadence.com

I am unable to install PSpice for TI on my Windows PC. The installer stops with the following error:

“Unable to access the URL required for installation. Check if URL is accessible and then try again.”

The error description is displayed in Korean and translates to:

CC3235SF: LAUNCHXL-CC3235SF用UniFlash无法进行烧录

CAO SHENG — Mon, 31 Aug 2026 08:47:42 GMT

Part Number: CC3235SF
Other Parts Discussed in Thread: UNIFLASH,

我正在使用 UniFlash 8.8.1 版本。最初，我成功地通过官方的 simplelink_cc32xx_sdk_7_10_00_13 将 bin 文件烧录到设备中。随后，在“Program Image”功能中，我又烧录了由 Code Composer Studio 编译生成的 sli 文件。SOP 跳线设置为 0-1-0，TX 和 RX 跳线均位于 TOP 位置。现在，我尝试再次通过 UniFlash 连接 CC3235SF 进行烧录，但一直收到“BootLoaderError: Timeout reading data”错误。有哪些有效的排查方法可以解决这个问题？

目前，我已经确认 TX、RX 和 SOP 跳线连接正确。是否存在因一次性安全策略导致 UART 烧录被永久禁用的可能性

Hello, TI experts

It seems that the latest SDK version of cc3200 is 1.5.0. Which CCS should I choose? The version of launchpad is v4.1. Thanks.

I also feel hard about IDE version when I use these old chips, As the web page always shows the latest version, but not fit for the old chip. Could you give me some advices?

CC3351: Port and adapt CC3351 on I.MX 93

Part Number: CC3351

Hi, Ti

I am currently porting and adapting the CC3351 WIFI & Bluetooth chip on IMX.93 with the kernel version 6.12. Following the instructions in file:///D:/ti/cc33xx_linux_package_1_0_2_10/cc33xx/docs/html/linux/kernel-porting-guide.html, I have successfully applied two patches to the kernel:

1. patch -p0 < /data/zs/test/linux-imx/drivers/net/wireless/ti/cc33xx_linux_package_1_0_2_10/cc33xx/patches/cc33xx_patch

2. patch -p1 < /data/zs/test/cc33xx-linux-mpu-ports/6.12.y/0001-drivers-cc33xx-forward-port-cc33xx-1.0.2.10-SDK-to-6.patch

Subsequently, I made changes to the corresponding device tree based on the /6.1.y/arm64-dts-enable-cc33xx-on-imx93-9x9-qsb.patch for the 6.1 kernel version, as follows:

When I compiled the WiFi into a kernel module and loaded it into the system, the following error messages appeared. I'm unable to pinpoint where the problem is. Could you give me some suggestions?

CC3235S: JTAG下载线问题

Part Number: CC3235S

TI工程师你好，

我将SOP2 连接至3.3V 烧录模式时，将16号引脚作为GPIO使用，并烧录了

我现在连接测试时无法连接到设备

请问是因为我将TDI作为普通GPIO烧录的原因吗，如果是真个原因我应该如何解决呢，

感谢

CC3235S: Does the CC3235S chip support DFS in the 5150-5350 MHz frequency band? If it does, please provide the firmware that supports DFS.

Gong Yao — Mon, 01 Sep 2025 05:59:28 GMT

Part Number: CC3235S
Other Parts Discussed in Thread: UNIFLASH

We are about to conduct SRRC certification for the CC3235S module.

1、Please provide the firmware version(s) and the corresponding firmware that support the certification testing.

2、What type of DFS is it? Does it support master devices or slave devices? If it is a slave device, does it support radar wave detection?

3、Is the interference avoidance type pre-transmission search or monitoring and avoidance? Is it frame structure-based non-frequency hopping or load-based non-frequency hopping?

M2-CC3351: M2-CC3351，模组复位信号(P23引脚)需在外部连接器添加上拉电阻的原因

jianbin liu — Tue, 12 Aug 2025 04:08:29 GMT

Part Number: M2-CC3351

我们在调试您邮寄过来的WIFI模组(型号M2-CC3351)时，发现一个现象，如下：

1.MMC2_RESET_N为高电平时(测量M.2连接器处)，WIFI模组板载复位指示灯没有点亮，测量模组U3位号的输出位置R6为低电平；

2.此时若在MMC2_RESET_N(M.2连接器处)飞线一（10K）上拉电阻到1.8V(SOCDVDD1V8)，重复断电/上电测试，上电时测量R6为高电平，同时复位指示灯点亮。

烦请帮忙确认下具体原因。

3.我们该部分电路原理设计图如下：

4.贵司邮寄过来的WIFI模组图示如下：
