你好,
我在OMAP-L138单板上使用Winbond公司的并行NOR FLASH,型号W29GL256SH9C(1.8V EMIFA总线),现在通过串口烧写工具sfh_omap-l138.exe擦除和烧写失败,打印如下:
擦除命令:

Waiting for SFT on the OMAP-L138...(停在这里)
因为我在单板上还有一个MCP,型号为MT29C2G24MAA (NAND+MDDR),使用下列擦除命令和烧写命令都正常的。
擦除命令:
sfh_OMAP-L138.exe -p com5 -flashtype NAND -erase
pause
请问,要想烧写并行NOR FLASH,我需要修改
执行SFT时会检查一下DDR写,读校验,如果校验不对,就出现上面的错误信息。要改一下device.c里的DDR参数,具体请参考下面的wiki网站。

你好,
我单板上有SPI FLASH,NOR FLASH,NAND FLASH,其中SPI和NAND都是可以烧写的。就只有NOR FLASH不能烧写。应该不是DDR参数的问题吧。
Winbond公司的并行NOR FLASH,型号W29GL256SH9C,要想使用sfh_OMAP-L138.exe烧写NOR FLASH,需要重新改Serial_Boot_and_Flash_Loading_Utility里面的代码吗?
我仿真器接口也有,是否可以通过仿真器试试?
谢谢!
jtag口烧写程序在下面的路径下OMAP-L138_FlashAndBootUtils_2_40\OMAP-L138\CCS\NORWriter 。
异步memory的设置在OMAP-L138_FlashAndBootUtils_2_40\OMAP-L138\Common\src\device_async_mem.c和OMAP-L138/Common/include/device_async_mem.h里。
你好,
我利用nor-flash-writer-03.20.00.14工程,使用仿真器烧写NOR FLASH失败,NOR FLASH型号:W29GL256SH9C(华邦电子),打印如下:
Starting OMAP-L138 NORWriter.
CFI Query...passed.
NOR Initialization:
Command Set: Unknown(停在这里了)
有什么好的建议?谢谢!
看了一下norwriter源码,不支持winbond flash。
// Supported Flash Manufacturers
typedef enum _NOR_MANF_ID_
{
UNKNOWN_ID = 0x00,
AMD = 0x01,
FUJITSU = 0x04,
INTEL = 0x89,
MICRON = 0x2C,
SAMSUNG = 0xEC,
SHARP = 0xB0
}
NOR_ManfID;
那要自己写烧写代码了。
