嵌入式实操----基于RT1170 移植memtester做SDRAM测试（二十五）
本文主要是通过迁移的思维，记录本人初次使用NXP MCUXpresso SDK API进行BSP开发
1. 移植来源
reference:
https://blog.51cto.com/henjay724/2711883
https://github.com/JayHeng/cortex-m-apps
由于RT1170上面没有SDRAM的压力测试工具，所以通过移植memtester工程至SoC,用于SDRAM的测量。2. 应用
复制memtester目前至工程
将相关文件添加入工程当中
将添加相关的头文件路径：
增加相关的测试代码如下：diff --git a/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c b/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c index 2a3c5cca..6be89002 100644 --- a/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c +++ b/SDK_2.8.0_MIMXRT1170-EAR3/boards/easyarm-rt1170-revb/driver_examples/gpio_bootloader/led_output/cm7/gpio_led_output.c @@ -12,7 +12,7 @@ #include "fsl_lpuart.h" #include "fsl_flexspi.h" #include "fsl_cache.h" - +#include "fsl_clock.h" #include "evkmimxrt1170_flexspi_nor_config.h" #include "pin_mux.h" @@ -20,6 +20,7 @@ #include "bsp_sdram.h" #include "bsp_sdram_test.h" #include "app.h" +#include "memtester.h" /******************************************************************************* * Definitions ******************************************************************************/ @@ -42,7 +43,17 @@ extern void dump_build_info(void); /******************************************************************************* * Variables ******************************************************************************/ +typedef struct _semc_test_config { + uint32_t baseAddr; + uint32_t testSize; + uint32_t loopNum; + uint32_t dramFreq; + uint32_t enableCache; +} semc_test_config_t; + +int fail_stop = 1; +char memsuffix = 'B'; /******************************************************************************* * Code ******************************************************************************/ @@ -478,6 +489,30 @@ int main(void) SEMC_SDRAMReadWrite16Bit(); /* 8Bit data read and write. */ SEMC_SDRAMReadWrite8Bit(); + + semc_test_config_t testConfig; + testConfig.baseAddr = 0x80000000; + testConfig.testSize = 32 * 1024 * 1024; + testConfig.loopNum = 1; + testConfig.dramFreq = CLOCK_GetRootClockFreq(kCLOCK_Root_Semc); + testConfig.enableCache = 0; + + if (!testConfig.enableCache) { + /* Disable D cache */ + SCB_DisableDCache(); + } + + PRINTF("\r\n########## Print out from target board ##########\r\n"); + PRINTF("\r\nSDRAM r/w test settings:\r\n"); + PRINTF(" Base Addr: 0x%x;\r\n", testConfig.baseAddr); + PRINTF(" Test Size: %d Bytes;\r\n", testConfig.testSize); + PRINTF(" Test Loop: %d;\r\n", testConfig.loopNum); + PRINTF(" SDRAM Freq: %d Hz;\r\n",testConfig.dramFreq); + PRINTF(" Enable Cache: %d;\r\n\r\n", testConfig.enableCache); + + /* Run memory stress test: 64KByte, loop=1, page_size = 1kbyte */ + memtester_main(testConfig.baseAddr, testConfig.testSize, &memsuffix, testConfig.loopNum, (1*1024)); + #endif // BSP_SDRAM_TEST- 1

3. 总结
有比较过memtester 4.5.1与参考移植版本memtester 4.5.0 相关文件之间的区别
- 主要是printf函数的移植。
- 主要是注掉跨平台代码的判断。
- 去除一些flush exit等函数。
- 找到对应的main入口函数，重写mian函数，并增加相关的参数memtester_main。
希望对各位读者帮助。
