CC3551E: CC3551E power supply issue and crystal issue

teng zeng — Wed, 27 May 2026 08:32:22 GMT

Part Number: CC3551E

1.In the SCH reference design for CC3551E , are the 3.3V and 1.8V voltages supplied by LDO or DCDC?if using DCDC for 3.3V and 1.8V,which will affect the performance of Wifi/BLE?

2.Can use the frequency tolerance ±7ppm &load capacitance(CL) 8pF as the 52Mhz main crystal?which will affect the performance of Wifi/BLE?

CC3351: CC3351: 使用 Nuttx RTOS 點亮 BP-CC3351

Austin Chen — Tue, 24 Mar 2026 07:01:54 GMT

Part Number: CC3351

Hi TI team,

我們嘗試將 TI 的 STM32 MCU for RTOS 範例程式碼移植到我們的系統 (Nuttx) 上。目前，我們可以運行到您的「獲取設備資訊」階段。

但會遇到 CRC error 以及 card busy 的問題，導致無法成功 briung up.

這是我們的設計流程，目前卡在Step3 會出現上面的 card busy 以及 CRC error ，請問流程是否有誤?

以下是邏輯分析儀工具，以及記錄檔

感謝您

AM2434: Does the AM2434+BP3351 development board combination support the sdio interface

Bill Gates — Wed, 21 Jan 2026 12:37:49 GMT

Part Number: AM2434
Other Parts Discussed in Thread: CC3351, LP-AM243,

Does the LP-AM243 and CC3351 support the sdio interface in the RTOS system and can you provide an example of the code implementation of the sdio interface.I only found support for the SPI interface in the user guidance document, not for the SDIO interface.

AM2434: How to set the 4-bit mode and 1-bit mode of sdio for AM2434 development board+BP3351 module

Bill Gates — Tue, 20 Jan 2026 12:42:55 GMT

Part Number: AM2434
Other Parts Discussed in Thread: SYSCONFIG

The system is FreeRTOS.Can the mode of sdio be set? Where can the 4-bit mode and 1-bit mode be set in the code.

AM2434: LP-AM243 development board+BP-CC3351 development board cannot start WiFi application after burning according to the document instructions.

After following this document:CC33XX MCU User's Guide , the WiFi application did not start and remained stuck on "Image loading done, switching to application ..." interface.What is the reason for this?

CC2564C: Regarding the Bluetooth protocol stack of CC2564C's BLUEtopia

Vayne Li — Mon, 24 Nov 2025 02:24:23 GMT

Part Number: CC2564C

Hi Teams,

My customer is planning to use CC2564C for development,
Can you provide the source code for the Bluetooth protocol stack of BLUEtopia? For their development purposes.
If unable to provide, can you provide relevant information such as user guidance documents? Thank you~
They are embedded system applications, with the main chip using Zhixin's Z20K148MCMQLT.

Thank you

BR~

CC3235MODAS: Inquiry regarding additional antenna certification for CC3235 in Japan (MIC)

Benjamin Chuang — Tue, 18 Nov 2025 01:29:30 GMT

Hi Ti team,

Our product is planned for sale in Japan. Can we apply for an additional antenna to be listed for our CC3235 module certification?

Thanks.

Best regards,

CC3351: Port and adapt CC3351 on I.MX 93

s z — Tue, 28 Oct 2025 09:21:54 GMT

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?

The error log is as follows:

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.

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：

官方提供的CC3100MOD SDK，是不是不需要开发工作，编译完直接下载到CC3100里面就可以直接工作？

我依照cc33xx_mcu_package_R5內的AM243 Guide步驟去操作

我目前使用CCS 20.2.0搭配mcu_plus_sdk_am243x_11_00_00_15去編譯CC3xx_thick_mac_network_terminal來產出cc3xxx_network_terminal.appimage

在使用python來燒錄program_application_and_wifi_fw.cfg

內容分別是

目前CC3235SF需要做CE认证，遇到需要自适应测试和blocking测试，对应的标准是EN300328，4.3.2.6是自适应要求，4.3.2.11是blocking的要求.请问是否有相应的固件可以对应测试。如果没有固件，我该怎么在现有SDK中修改实现测试的要求。

Part Number: BP-CC3351
Other Parts Discussed in Thread: CC3351, CC3200, LP-AM243

我們目前tm4c129exl是使用SPI溝通其他 wifi module

最近需要更換wifi module，目前有借到BP-CC3351

我從Mcu CC33XX User's Guide R4看應該同樣用spi與其通訊

但我未找到SPI通訊協定內容

請問我要如何進行測試

另外CC3351是否能像CC3200一樣進行編輯
