S32K312ではFlexCANは動作しません。 こんにちはNXPの皆さん。 サンプルコード(FreeRTOS_Toggle_Led_Example_S32K312)でFlexCAN機能を試してみたいのですが、うまくいきません。 私は問題のクエリにロジックアナライザを使用していますが、CAN TX / RXピンは期待されていません、私を助けてください、多くの感謝。 1.MCUピン29(CAN-RX):常に奇妙な信号が表示されます。 2.MCUピン54(CAN-TX):常に高い。 環境： 1.SW32K3 FreeRTOS 10.6.0 バージョン 4.0.0 は S32K3 RTD 4.0.0 に基づいています 2.FlexCANの速度500KBpsを設定します 3.CANトランシーバー(TI TCAN1044)を使用しています 愛着： 20241223-FreeRTOS_Toggle_Led_Example_S32K312.7z 20241223-LA_CAN_screenshot.png Re:S32K312ではFlexCANについては機能しません。 こんにちはセンレント: すみません、私のせいです。ロジックアナライザーに関する問題を見つけました。スコープとLAを同時に使いましたが、 そしてスコープは正常で奇妙な波ではないので、LAの別のチャンネルを変更しましたが、波は完璧です、再び感謝します。 いってらっしゃい。 Re:S32K312ではFlexCANについては機能しません。 こんにちはNXPの皆さん。 あなたが修正してくれてありがとう。この日の朝、私は flexCAN プロトコルクロックを FIRC クロックソースとして 24Mhz に変更し、ビットレートを 500kbps に調整してみましたが、LA や PCAN-viewer で CAN バス機能について動作できるのですが、まだ CAN-RX の奇妙なデータ波が残っています。ちょうど今、私はテストのためにあなたの変更されたワークショップを使用しましたが、結果は同じです。CAN-RXピンのアイデアはありますか?感謝。 追伸。あなたの改造ワークショップからLAで波の写真を添付としてキャプチャしました。 Re:S32K312ではFlexCANについては機能しません。 こんにちはNXPの皆さん。 ちょうど今、あなたが推奨したExample_S32K358_FlexCAN_Ip_TXRX_ISR_rtd400から移植コードを変更しました、 GPIOが正常であることを確認しましたが、結果は同じ失敗です、できるだけ早く私を助けてください、ありがとう。 愛着： 20241223-test_CAN2.7z 20241223-20231223-CAN_transceiver_schematic.png Re:S32K312ではFlexCANについては機能しません。 こんにちはNXPの皆さん。 ご提案ありがとうございます。からS32K312と移植のサンプルコードの新しいプロジェクトを作成しました 「S32KXX AUTOSAR R21-11 RTD 4.0.0」D2311 Example Projects\FlexCAN_Ip_Example_S32K344"ですが、 結果は同じです。実は、CAN-RXの信号がいつも変な波を吐いているのが気になるところです。 ピンセッティングの問題など、何か問題があるのでしょうか?

FS26 FCCU1 单PWM监控 你好，有人能告诉我 FS2633D FCCU1 PWM 监控的配置应该是什么吗？ 我已将 FCCU_CFG 配置为 110，以使用 FCCU1 PWM 监控和 FCCU2 上的输入电平监控。 即使我没有对 FCCU1 引脚施加任何 PWM 波，我也无法使重置正常工作。我的看门狗重置工作正常，因此重置连接中没有硬件问题。 此外，如果有人能给我一个 FCCU1 上有效 PWM 波的例子，或者仅仅从占空比和频率的角度进行解释，那就太好了，因为数据表有点令人困惑。如果能做到这一点，将会有很大帮助。 非常感谢您。 功能安全 电源解决方案 回复：FS26 FCCU1 单PWM监控 因此，当波形较低时，其黑白范围应为 51-80us，而当波形较高时，其黑白范围应为 6-10？ 我是否正确或者有什么不同？ 为什么 10-45 KHz 的“良好”PWM 范围与不良低频和不良高频不同，根据该范围，不良频率不应该小于 10KHz 且大于 45KHz 吗？ 我错过了什么？ 回复：FS26 FCCU1 单PWM监控 我的主要困惑是关于 PULSE_FCCU_HF 和 PULSE_FCCU_LF 时间。它们与波的占空比有关吗？ 如果良好的频率范围在 10-45KHz 之间，那么不良频率怎么会大于 90KHz？ 如果我只给出任意占空比的 30KHz（良好频率）的 PWM，是否不会出现故障？或者有什么不同？

FS26 FCCU1 single PWM monitoring Hi, can please someone tell me what should be the configuration for FS2633D FCCU1 PWM monitoring?  I have configured FCCU_CFG to 110 to use FCCU1 PWM monitoring and input level monitoring on FCCU2. I can't get the reset to working even if I don't apply any PWM wave to FCCU1 pin. My watchdog reset is working fine so no hardware issue in the reset connection.  Also, it would be great if someone can give me an example of a valid PWM wave on FCCU1 or just explain in terms of duty cycle and frequency because the datasheet makes it a bit confusing. It would be a great help if this can be done.  Thanks a lot. Functional Safety Power solution Re: FS26 FCCU1 single PWM monitoring HI : For example, tPULSE_FCCU_HF =8us, that means both high and low duration time is 8us, T=16us, corresponding PWM frequency is 62.5KHZ(50% duty cycle). “tPULSE_FCCU_HF”  means FCCU will report a failure if High or low pulse duration is smaller than 8us(typ), 6us(min), 10us(max). “tPULSE_FCCU_LF” means FCCU will report a failure if  High or low pulse duration is larger than 64us(typ), 51us(min), 80us(max). As a result: FCCU is 100% good when high or low duration time is within 10us~51us(frequency is within 9.8K~50K), there is some buffer considered, so  FCCU12_GF = 10KHZ~45KHZ. FCCU is 100% bad when high or low duration time is below 6us or above 80us(frequency is >83K or <6.25K), there is some buffer considered, so FFCCU12_BLF =5KHZ max and FFCCU12_BHF =90KHZ min. Re: FS26 FCCU1 single PWM monitoring So, when the wave is low it should b/w 51-80us and when its high it should be b/w 6-10? Am I correct or is it something different? And why the "good" PWM range of 10-45 KHz is different than the bad low and bad high frequency, shouldn't the bad frequency be less than 10KHz and greater than 45KHz according to that range? What am I missing? Re: FS26 FCCU1 single PWM monitoring 1:You can get the detection time here for the high or low level on PWN monitoring : 2:bad frequency are below showed: <5KHZ or >90KHZ Re: FS26 FCCU1 single PWM monitoring My main confusion is regarding the PULSE_FCCU_HF and PULSE_FCCU_LF time. Are they related to the duty cycle of the wave? And if good frequency range is between 10-45KHz then how is bad frequency is greater than 90KHz?  Will there be no fault if I just give a PWM of 30KHz (good frequency) of any duty cycle? Or is it something different? Re: FS26 FCCU1 single PWM monitoring Hi aad1tya We list all of the configuration information about FCCU PWM/lever monitoring in datasheet page188-190--->20.7.3 FCCU single PWM monitoring activated For example FCCU configure PWM frequency /level threshold : You can read them. Hope this could help you!

Layerscape Hardware Security Module(HSM) storage questions Hello, In the LSDK User Guide mentions that the SoCs can internally store keys using an HSM. "NXP SoCs such as LS1046A can store keys securely using built-in SoC capabilities - virtual HSM. With such devices, sensitive private keys never leave the device and cryptographic operations are performed on this virtual HSM"(LSDKUG-Rev21.08, CH 6.5.1). I could not find a reference to whether it is stored using secure non-volatile storage (SNVS), or if it is stored in volatile memory requiring a battery connected such as the with the "Battery Backed Security Monitor supply". Does the SoC need to keep some voltage after powering off to keep the keys stored securely? And just to confirm, this feature applies to all arm trusted firmware(TFA) enabled CPUs? QorIQ LS1 Devices Re: Layerscape Hardware Security Module(HSM) storage questions Hello @jvfausto  Hope this post finds you well, They are stored in a non-volatile memory. BR, Hector V Re: Layerscape Hardware Security Module(HSM) storage questions Hello @jvfausto  Hope this email finds you, This email is to inform that I keep working on the solution on this case. I’ll keep you informed on the process, Have a great day.   BR, Hector Villarruel

FS26 FCCU1シングルPWMモニタリング こんにちは、誰かが私にFS2633D FCCU1 PWM監視の構成を教えてください。 FCCU_CFG to 110 を FCCU1 PWM 監視と FCCU2 の入力レベル 監視を使用するように構成しました。 FCCU1ピンにPWM波を適用しないと、リセットが機能しません。ウォッチドッグのリセットは正常に機能しているため、リセット接続にハードウェアの問題はありません。 また、FCCU1の有効なPWM波の例をどなたか教えていただけると幸いです。または、データシートが少し混乱させるため、デューティサイクルと周波数の観点から説明してください。これができれば、とても助かります。 どうもありがとうございます。 機能安全 電源ソリューション 日時:FS26 FCCU1シングルPWMモニタリング では、波が低いときは白黒51-80us、高いときは白黒6-10になるべきなのでしょうか? 私は正しいですか、それとも何か違うのですか? また、10〜45 KHzの「良い」PWM範囲が悪い低周波数や悪い高周波と異なるのはなぜですか、その範囲に応じて、悪い周波数は10KHz未満で45KHzを超えるべきではありませんか? 何が足りないのか? 日時:FS26 FCCU1シングルPWMモニタリング 私の主な混乱は、PULSE_FCCU_HFとPULSE_FCCU_LF時間に関するものです。それらは波のデューティサイクルに関連していますか? また、良好な周波数範囲が10〜45KHzの場合、不良周波数はどのようにして90KHzを超えますか? 任意のデューティサイクルで30KHz(良好な周波数)のPWMを与えるだけで問題はありませんか?それとも何か違うのでしょうか?

Please let me know how to notify when 'Disassociate' is issued from the connected device. Dear NXP Support Team, I am currently working with 88W8887 and require assistance with Access Point mode. When a STA device connected to the access point is disconnected, the STA device issues a 'Disassociate'. Is there a way to notify when this 'Disassociate' is issued? Additionally, is there a way to issue a disconnection notification when the connection between AP and STA is severed by issuing this "Disassociate"? I am using "SD-WLAN-UART-BT-8887-U16-MMC-W15.87.19.p64-15.100.19.p64-C4X15704_A2-MGPL". ・Linux Kernel Version v3.18.24 ・hostapd Version：2.10 ・wpa_supplicant Version：2.10 I would greatly appreciate your guidance on the following points: Are there specific configurations or settings required for the TCC8971（Telechips） to operate in AP mode effectively with the Marvell 88W8887 WiFi device? Are there any firmware updates or specific versions that support AP mode more reliably? Any additional troubleshooting steps or tools that I can use to diagnose and resolve the connection issues? Thank you for your time and assistance, Best regards, Hiroyuki Kohchi Protocol: Wi-Fi Re: Please let me know how to notify when 'Disassociate' is issued from the connected device.

Any additional troubleshooting steps or tools that I can use to diagnose and resolve the connection issues? ==>You can refer to Feature Configuration Guide for NXP-based Wireless Modules on i.MX 8M Quad EVK - User manual. In section 3 Wi-Fi driver debugging, it includes some guide steps for Wi-Fi debug. And specially for connection issues, we usually capture dmesg, wpa_supplicant journal logs and Wi-Fi OTA logs to see what happened.  How to capture dmesg logs: On Linux terminal, directly execute: dmesg > log.log  It will save the dmesg logs into log.log file and saved on your host platform. How to capture wpa_supplicant journal logs: You can use below steps to enable the supplicant logs: 1. boot up the board 2. killall wpa_supplicant 3. open "vi /lib/systemd/system/wpa_supplicant.service"  4. add -ddd at end "ExecStart=/usr/sbin/wpa_supplicant -u -ddd" 5. reboot the board 6. Run the scenario using nmcli 7. run journalctl -a -b to capture the supplicant logs How to capture Wi-Fi OTA logsWith wireshark or Ominipeek and Wi-Fi card which supported monitor mode to capture Wi-Fi OTA logs. To resolve connection issue, we need to identify what's the root cause, is from our side or from remote side. From driver side or FW side. Our Wi-Fi chip side or your application side. Anyway, once we find any evidence shows that the issue is from our Wi-Fi side, we will try to fix it. And you do not need to do anything except validation. Please feel free to create case if need our support on our Wi-Fi chips. Best regards, Christine.

TX_CLK Signal Configuration in 100BASE-T1 Test Mode on SJA1110 Hi  We are currently testing the 100BASE-T1 test mode on the SJA1110 switch. During the tests, we found that the Jitter (SLAVE) requires an additional TX_CLK signal. The Software User Manual for the SJA1110 indicates that additional configuration is necessary to switch LOC_WAKE_IN to TX_CLK. We switching the PHY into different testmodes, and some of the test modes have passed. However, we still do not observe any signal on TX_CLK. We also reviewed the switch_config_sja1110evm example in S32 Design Studio, where only the test mode is configured. Could you please advise if any additional configuration is required to enable the TX_CLK signal? Thank you for your support. Re: TX_CLK Signal Configuration in 100BASE-T1 Test Mode on SJA1110 Hello, @steven-Yeh  Thanks for the post. Since this is SJA1110EVM related questions, which is not directly related with S32G, I suggest posting it in the following forum: https://community.nxp.com/t5/Other-NXP-Products/bd-p/other For them to provide more proper support. Sorry for your inconvenience. Best Regards Chenyin

S32K344 Hardware CRC issue Hi, there I used the crc of the S32K344 with hardware calculation type to calculate the CRC of the pflash, but I couldn't get the result. I don't know why. Please help me. the attached is my test code. RTD:3.0 S32DS:3.5   Re: S32K344 Hardware CRC issue Hi @ZDDL  Which is the expected result? I ask you to please test your code with just a value to verify the behavior. Also, have you already try the Crc_Ip_Example? My recommendation is to take a look at this example, which you might find useful. BR, VaneB

Dma transfer on S32K310  while i am testing the Dma function on S32K310, i find that the destination buffer is not updated. then tried to read the Dma status, this is the value of error register. this is how the variables initialized Re: Dma transfer on S32K310 thank you, good solution! Re: Dma transfer on S32K310 Hi @LeoYang-, As per the debug session that I checked with you, we can conclude that the cause is: somehow, the CH0_ES[ERR] bit was set before calling the Dma_Ip_Init() function, and after, the destination address and source address can't be written into the DADDR and SADDR registers by Dma_Ip_SetLogicChannelTransferList() function. This is the solution: write 1 to clear the CH0_ES[ERR] bit before calling the Dma_Ip_Init() function. Best regards, Dan
