AM3359： RTOS parallel NOR boot

Did you mean the following macro?

#if defined (ICEV2_AM335X)
#define BOARD_FLASH_ID         BOARD_FLASH_ID_MT29W160EB

I think that is okay, because BOARD_FLASH_ID_MT29W160EB is defined in board\src\flash\include\board_flash.h:

#define BOARD_FLASH_ID_MT29W160EB (0x2249U) /**< Micron 2MB NOR flash */

And it matches the device id defined in board\src\flash\nor\device\m29w160eb.h:

#define NOR_DEVICE_ID (0x2249U) /* Device ID */

I figured out why the test failed. The default pinmux for AM335x ICE v2 in the PDK is not for parallel NOR flash. Below is what I did to make GPMC_Test_icev2AM335x_armTestProject work:

1. Update pinumx file:

• Load pdk_am335x_1_0_17\packages\ti\starterware\tools\pinmux_config\am335x\icev2_config.pinmux into PINMUX tool.
• Add GPMC and choose "Non Multiplexed 16b NOR type - Asynchronous" as the Use Case.
• Resolve all pin conflicts and save am335x_pinmux_data.c.

2. Rebuild board library:

• Update pdk_am335x_1_0_17\packages\ti\starterware\board\am335x\am335x_icev2_pinmux_data.c by replacing the definition of gGpmc0PinCfg[] by what's defined in am335x_pinmux_data.c which was saved in previous step.

static pinmuxPerCfg_t gGpmc0PinCfg[] =
{
    // Replace the content with what's in the updated pinmux data file - am335x_pinmux_data.c

}

• Make a copy of folder pdk_am335x_1_0_17\packages\ti\board\lib\icev2AM335x.
• Rebuild board library:

C:\ti\pdk_am335x_1_0_17\packages>pdksetupenv.bat
C:\ti\pdk_am335x_1_0_17\packages\ti\board>gmake LIMIT_SOCS=am335x LIMIT_BOARDS=icev2AM335x

3. Add the following line to main_gpmc_flash_test.c of GPMC_Test_icev2AM335x_armTestProject:

#define TEST_GPMC_FLASH_WRITE

4. Rebuild the project and ran the test.

Below is what I got after running the code.

This validates the GPMC NOR flashing code works properly. So your customer can write their own flash writer based on this example.
