S32K3 Arm® Cortex®-M7 based MCUs simplifying software development for automotive and industrial The S32K3 family includes scalable 32-bit Arm Cortex-M7 based MCUs in single, dual and Lockstep The S32 Safety Software Framework (SAF) includes components that provide the safety foundation for ISO 26262‑compliant applications and integrates Safety 注意 S32K11x 器件的SRAM_L 不受ECC 保护。 用作系统RAM 的FlexRAM 没有ECC。 LPUART 和FlexCAN RAM受ECC保护。 SRAM 的复位状态未知,因此数据可能包含随机数据。 对任何地址的第一 文章浏览阅读461次，点赞3次，收藏2次。RAM必须写才算初始化，但是实际在main函数内写入时，会触发异常，从而进入错误中断，实测调试发现在汇编启动部分就不会。怀疑cache的问题，所以加上一 Hi Ragus, Yes, your understanding is correct. 3k次，点赞3次，收藏20次。S32K144之SRAM ECC错误浅谈之前的一片文章摘录了嵌入式MCU存储器ECC工作原理，大家可以简单了解下 本文基于NXP的S32K1xx系列的芯片，来分析SRAM的ECC机制以及通过故障注入方式来验证以下两种类型故障。 1，单比特翻转错误2，多比特不可纠正错误话不 Hi All, I am working on S32K11x platform. Best Regards, Robin The S32K3 family includes scalable 32-bit Arm Cortex-M7 based MCUs in single, dual, and lockstep core configurations supporting ASIL B/D safety applications. This application note is intended to describe how the ECC protection is implemented in S32K1xx family and understand the particular ECC event response for S32K14x and S32K11x devices. 3k次，点赞5次，收藏18次。本文介绍了S32K3芯片如何通过EDC、XBIC和ECC三种方法确保数据完整性，并提及CRC硬件模块作为额外保障手段。 文章浏览阅读6. It is clear from the S32K1xx Series Reference Manual that both sections of RAM is protected as well as how to detect S32K FlexIO Peripheral Capabilities FlexIO = Flexible Input and Output peripheral Programmable logic for complex output waveform generation Emulation of standard communication interfaces: −UART, . pdf document, it mentions that S32K3XX supports Error-Correcting Code (ECC) function. If the initialization is omitted then any read or write to the Can you provide an example of processing and testing ECC of C40? The ECC is covered by SAF (safety application framework), demo code is included along with documentation in the SAFE S32K1xx 系列中使用的ECC 方法提供单错误纠正(SEC )和双错误检测(DED)功能。 本应用笔记旨在描述如何在S32K1xx 系列中实现ECC 保护,并了解S32K14x 和S32K11x 器件的特定ECC事件响应。 同时 本文介绍了S32K3芯片如何通过EDC、XBIC和ECC三种方法确保数据完整性，并提及CRC硬件模块作为额外保障手段。 大家都知道，怎样保证数据 Most probably the first read attempt to any address would generate non-correctable ECC error. Anybody knows how to verify ECC function on 文章浏览阅读6. We are trying to understand which memory types of the S32K is protected by ECC. Only the ECC-protected SRAM needs to be initialized. Some question related to safety manual assumptions about ECC (sram and flash): Assumption: [SM_111] The ECC SRAM reporting has to be enabled by the Memory and memory interfaces — Up to 12 MB program flash memory with ECC — Up to 256 KB of flexible program or data flash memory — Up to 2304 KB SRAM with ECC, includes 384 KB of TCM 举个例子，在K3的Flash中是有ECC校验机制的，那么在这里，Data bits即为数据的位数，而Check bits即为ECC校验码的位数。 31个通道搞清楚了，那么EIM是怎 Hello, I am using S32K118 EVB. I did go through the Datasheet and also this example link: Example S32K14x Scalable automotive MCUs built on Arm Cortex-M cores, featuring ASIL functional safety, hardware security and full software development tools Hi Sir, In S32K3xxDS. Features include a hardware security Hello, We want to enable ECC check on SRAM for our existing project on S32K144. My question: is there a way to NXP S32K microcontrollers, based on the Arm® Cortex®-M series core, offer scalability, high-performance and low-power consumption tailored for The ITCM and DTCM must be properly initialized with correct ECC before any read operation to avoid any code runaway or software malfucntion or core lockup. 因此，故障注入只能来通过反转CheckBit Bus的数据来检查状态ECC机制是否完善。当实际MCU工作 注：上面说的复位，是博主实际对ReadData Bus 上做比特翻转操作之后的结论。即：步骤1）定义反转的读取总线上的Bit（Word1）。 The ECC logic implemented in the S32K1xx Flash memory can correct single-bit fault automatically and can detect multiple-bit fault in each Just like the TCM memory, all the SRAM memory must be initialized to avoid ECC errors and this can be done by the core or the DMA as well. According to the safety manual, reading flash memory can detect the double-bit uncorrectable error.
