问答对人有帮助，内容完整，我也想知道答案 0 我使用sfh_OMAP-L138.exe串口烧写工具来烧写UBL、UBOOT时，在擦除的过程中总是停止在Waiting for SFT on the OMAP-L138...这，具体信息如下： C:temp>sfh_OMAP-L138.exe -erase -targetType OMAPL138 -flashType NAND -P COM4 ----------------------------------------------------- TI Serial Flasher Host Program for OMAP-L138 (C) 2010, Texas Instruments, Inc.

答案对人有帮助，有参考价值 0 请问你是在EVM板还是自己的板上测试的？因为官方的EVM板子上面用的mDDR，如果你用的DDR2的话，需要改动sft工具。在device.c中，你可以改动最后一个mDDR的配置为DDR2的配置。配置的方法可以参考mDDR/DDR2 controller user guide。 Uint32 DEVICE_init() [ Uint32 status = E_PASS; // Ensure the kick registers are unlocked // Note these lines have no effect on 2.0 and later silicon DEVICE_kickLock(); DEVICE_kickUnlock(); SYSTEM->SUSPSRC &= ( (1 << 27) \| (1 << 22) \| (1 << 20) \| (1 << 5) \| (1 << 16)); #ifndef SKIP_LOW_LEVEL_INIT // System PSC Setup DEVICE_PSCInit(); // System PLL Setup if (status == E_PASS) [ #if defined(AM1808) // CPU(s) at 456 MHz status \|= DEVICE_PLL0Init(0, 18, 0, 0, 0, 18, 8); #else // CPU(s) at 300 MHz status \|= DEVICE_PLL0Init(0, 24, 0, 1, 0, 11, 5); #endif ] if (status == E_PASS) [ // mDDR @ 150MHz status \|= DEVICE_PLL1Init(24, 1, 0, 1, 2); ] // External Memory Timing Setup if (status == E_PASS) [ // Timings for mDDR at 150 MHz status \|= DEVICE_ExternalMemInit(0x000000C4, 0x0A034622, 0x1C912A08, 0x3811C700, 0x00000494, 0x00000000); ] #endif return status;
