FlexIO BiSS-C master: MA clock count cannot adapt to ACK period, CRC fails at 2.5 MHz I'm using the MIMXRT1186 with the SDK's flexio_biss_polling_transfer example to communicate with a BiSS-C absolute encoder (24-bit ST + 16-bit MT). Problem: At 500 kHz, CRC passes and position data is correct. At 2.5 MHz, CRC always fails. The encoder's ACK period is about 11.8 µs, which equals roughly 30 MA clock periods at 2.5 MHz. Oscilloscope observation shows that the FlexIO master sends a fixed number of MA clocks from the very beginning of the frame, without adjusting for the ACK period. The 30 ACK low-level bits are sampled into the 64-bit receive shifter, pushing the actual START + SCD data out of the shift window. FLEXIO_BISS_CalFrameHeadLen() returns values between 12 and 34, and BISS_VerifyFrame() calibration fails. What I understand about BiSS-C: The protocol requires MA to keep running during ACK, because the encoder needs those clocks to advance its internal state machine and eventually end ACK and send the START bit. So the correct master behavior is: MA keeps sending clocks from the start of the frame, including during ACK. The master monitors SL. The master continuously counts the MA clocks already sent. When SL goes high (ACK ends, START bit arrives), the master records how many clocks were consumed by ACK, then calculates how many more clocks are needed to complete the frame. My question: FlexIO's timer uses a fixed timerCompare value to send a predefined number of clocks in one shot. Is there any FlexIO mechanism to support the adaptive behavior above, i.e., dynamically adjusting the number of remaining MA clocks based on the SL edge during a frame? Specifically: Can FlexIO's timer use the SL edge as a trigger to stop, reset, or reload the timer, so that the master can determine when ACK has ended and then send the remaining clocks? If FlexIO cannot do this, what does NXP recommend for implementing a BiSS-C master that supports long ACK periods (e.g., eFlexPWM, LPSPI, or an FPGA-based solution)? Setup: MCUXpresso SDK for MIMXRT1186 Driver: fsl_flexio_biss.c / .h Oscilloscope monitoring MA (D02) and SL (D00) Thanks for any guidance. 回复： FlexIO BiSS-C master: MA clock count cannot adapt to ACK period, CRC fails at 2.5 MHz Update: NXP has released an official example that solves this issue.

在 IMX8MP 上启动 M7 核心后，启动 A53 核心时出现问题。 启动 M7 后，我尝试继续正常的启动过程：boota mmc1或 boot 此时，AAOS 无法正常启动。如果我不启动 M7，而是直接执行 `boota mmc1` 命令， AAOS 则可以正常启动。 因此，问题似乎与在启动 Cortex-A53/AAOS 之前启动 Cortex-M7 有关。 它显示异步系统错误。 Re: Issue regarding booting A53 core after booting M7 core on IMX8MP. 你好@Siva_Sachu 希望你一切都好。 请问能否提供重现问题的步骤？ 您是在 U-boot 中启动 M7 吗？ 顺祝商祺！ 萨拉斯。

为 IMX8 Nano 处理器实现 USB 尝试为 imx8 nano 实现 USB 功能，评估板布局显示 ID 引脚为浮空导线。它能在主机模式下工作吗？因为主机模式下 id 必须等于 0。 Re: implementing usb for imx8 nano processor 你好@Jayesh2408 希望你一切都好。 是的，只要通过软件强制控制器行为，浮空 ID 引脚在仅主机模式下也能完美工作。 您只需将设备树中的dr_mode属性从“ otg ”更改为“ host ”即可： &usbotg1 { dr_mode = "host"; hnp-disable; srp-disable; adp-disable; usb-role-switch; disable-over-current; samsung,picophy-pre-emp-curr-control = <3>; samsung,picophy-dc-vol-level-adjust = <7>; status = "okay"; port { usb1_drd_sw: endpoint { remote-endpoint = <&typec1_dr_sw>; }; }; }; 顺祝商祺！ 萨拉斯。

IMX8ナノプロセッサ向けのUSB実装 iMX8 NanoにUSBを実装しようとしていますが、評価ボードのレイアウトではIDピンの配線がフローティング状態になっています。ホストモードでも動作しますか？ホストモードではidを0にする必要があるからです。 Re: implementing usb for imx8 nano processor こんにちは、@Jayesh2408さん お元気でお過ごしのことと思います。 はい、フローティングIDピンはホストオンリーモードでは、ソフトウェアでコントローラーの動作を強制すれば問題なく動作します。 デバイスツリーの dr_mode プロパティを「otg」から「host」に変更すればいいです。 &usbotg1 { dr_mode = "host"; hnp-disable; srp-disable; adp-disable; usb-role-switch; disable-over-current; samsung,picophy-pre-emp-curr-control = <3>; samsung,picophy-dc-vol-level-adjust = <7>; status = "okay"; port { usb1_drd_sw: endpoint { remote-endpoint = <&typec1_dr_sw>; }; }; }; よろしくお願いいたします。 サラス。

i.MX93 power sequencing I am designing a low power PCB based around the i.MX93 and its recommended PMIC (PCA9451). The AN13917 power consumption measurement document suggests that in its lowest power mode (section 6.7.8) the SoC+DRAM power consumption should be ~174mW. However, the current measurements in the document are taken after the PMIC, so do not include any efficiency losses.  When calculating the actual expected power consumption, the vdd_ana_0p8 rail stands out as a very high consumer of energy. The 16.5mA current draw on this rail causes 69mW dissipation in the PMIC LDO (from a 5V input). This is ~60% of the efficiency losses. I would like to power this rail from a separate SMPS module (TI TPSM82821) to reduce these losses, however the i.MX93 datasheet has no definition of Tstep or Toff_step in the power rail sequencing requirements. Are there actually any timing requirements, or only sequencing? Would it be sensible to use VDD_SOC as the enable trigger (via a comparator) for the external SMPS, or are there better options to use? I'm assuming that the 0V8 will discharge faster than VDD_SOC during power down as the TPMS82821 has an output active discharge function. Re: i.MX93 power sequencing Hello, There is a time for Tstep or Toff_step in Table 6. PWRUP mode: tSTEP (Time to next power rail ON from prev rail POK):  2 ms tOFF_STEP (Time to next power rail off from prev rail off): 8 ms Also, you can use VDD_SOC as reference to trigger external regulator in power-up/power-off sequences. Best regards.

Ara2 Windows factory-test/runtime package unavailable I’m working with an Ara2 PCIe Accelerator on Windows. The hardware is detected correctly, PCIe/DMA initialization succeeds, and the AraProxyService is running. However, device initialization fails with the following error: Unsupported firmware version on device: 0 please update firmware. Current environment: Firmware: 14.34.0.0 Proxy: 1.1.0.0 SysAPI: 1.1.56.0 The Windows ARA2 User Guide references the factory-test-package-windows.zip file and the Qwen Windows demo package, but those attachments are not available to me through the article. Could someone from NXP please provide access to the current Windows factory-test package and the matching runtime/firmware package for the Ara2? This is currently blocking validation of the accelerator in an active Windows deployment.

implementing usb for imx8 nano processor trying to implement usb for imx8 nano, the eval board layout shows floating wire for Id pin. will it work for host mode? because id need to be =0 for host mode. Re: implementing usb for imx8 nano processor Hello @Jayesh2408  Hope you are doing very well. Yes, a floating ID pin will work perfectly fine for host-only mode, provided you force the controller behavior via software. You can just change the dr_mode property in device tree from "otg" to "host": &usbotg1 { dr_mode = "host"; hnp-disable; srp-disable; adp-disable; usb-role-switch; disable-over-current; samsung,picophy-pre-emp-curr-control = <3>; samsung,picophy-dc-vol-level-adjust = <7>; status = "okay"; port { usb1_drd_sw: endpoint { remote-endpoint = <&typec1_dr_sw>; }; }; }; Best regards, Salas.

PN7150/NCI: Unable to update MIFARE Classic 1K Sector Trailer with Custom Embedded Key B Hello NXP Community, I am working with a MIFARE Classic 1K card and an NXP PN7150 NFC controller running over the standard NCI protocol layer. I am trying to implement a provisioning feature where I write a custom secret password into Key B of a target sector (Sector 7), but the card chip consistently rejects the write command. Here is the exact state of my card and the implementation details: Current Sector 7 State: The sector is currently blank/unformatted. A read dump shows it is in the factory default state with access bits FF078069 and both Key A and Key B set to 0xFFFFFFFFFFFF. The Goal: I want to keep Key A as the read key, preserve the open access bit layout, and overwrite Key B with a personal custom key payload (0x01 0x02 0x03 0x04 0x05 0x06). The Issue: When I attempt to write the 16-byte raw block layout string (FFFFFFFFFFFFFF078069010203040506) to Block 3 (Sector 7 Trailer), the write transaction fails. Note: i did the card NDEF format with an App and access bytes are showing 7F078840 Any guidance would be greatly appreciated!   Kind Regards   Re: PN7150/NCI: Unable to update MIFARE Classic 1K Sector Trailer with Custom Embedded Key B Hello @Saqib1 Hope you are doing well. Please consider that PN7150 is Not Recommended for New Designs; we recommend using PN7160 instead. Additionally, MIFARE Classic is also Not Recommended for New Designs; MIFARE DESFire Light can be considered. Before sending the write command make sure the authentication with Key A (FFFFFFFFFFFFh) on block 1Fh (Sector 7 trailer) is performed successfully. Now, after authentication on block 1Fh, please verify that the write command is being sent following the procedure described in the MIFARE Classic EV1 1K datasheet, section 12.3. The WRITE operation consists of two parts that must be sent sequentially: Part 1: Send the command byte and block address, including CRC: A0 + XX +CRC where XX is the block address (e.g., 1Fh for the Sector 7 Trailer). The card must respond with ACK before proceeding. Part 2: Only after receiving the ACK, send the 16 bytes of data including CRC: [16 bytes payload] + CRC. The card will respond with a final ACK to confirm the write was accepted. Regards, Eduardo.

CLEV6630B 评估板（OM26630FDK） 我获得了 CLEV6630B 评估板 (OM26630FDK) 的 PDF 文件，请问我能否获得相同板型的 Altium PCB 文件，用于我们的定制设计？ Re: CLEV6630B eval board(OM26630FDK) 你好@R_Tony ， 希望你一切都好。 非常抱歉，该设备的唯一可用设计文件是CLRC6630B 原理图和布局图，以 PDF 格式提供。 给您带来的不便，敬请谅解。 问候， 爱德华多。
