EBOOT Porting : change Debug uart pin

Sam_Wong — Wed, 16 Jan 2013 18:24:34 GMT

Hi all,

Do anyone have modify WINCE700 EBOOT in i,mx53_SMD? I want to change the UART1 pin but failed

I had developed our own board based on i.mx53 QSB and it had already successfully run linux , ubuntu and android.

Now we would like to build WINCE700 on it based on BSP(iMX53_SMD ) . The difference of our board with QSB is

1. use i.mx536 instead of i.mx 535

2. UART : SMD use ( CSI0_DAT10: UART1_TX, CSI0_DAT11: UART1_RX)

but our board use (PATA_DIOW:UART1_TXD, PATA_DMACK:UART1_RXD)

Now our board can't use the eboot to start up but same eboot can boot on QSB. the following is what we modify, is it enough?

1. IO MUX:

C:\WINCE700\platform\iMX53_SMD\src\COMMON\SERIALUTILS\serialutils.c. we modify OALConfigSerialIOMUX as follow:

OAL_IOMUX_SET_MUX(pIOMUX, DDK_IOMUX_PIN_PATA_DIOW, DDK_IOMUX_PIN_MUXMODE_ALT3, DDK_IOMUX_PIN_SION_REGULAR);

OAL_IOMUX_SELECT_INPUT(pIOMUX,DDK_IOMUX_SELECT_INPUT_UART1_IPP_UART_RXD_MUX,3);

OAL_IOMUX_SET_MUX(pIOMUX, DDK_IOMUX_PIN_PATA_DMACK, DDK_IOMUX_PIN_MUXMODE_ALT3, DDK_IOMUX_PIN_SION_REGULAR);

2. Magic number:

we comment it as follow:

C:\WINCE700\platform\iMX53_SMD\SRC\BOOTLOADER\

COMMON\main.c function LoadBootCFG

//if (BootCfg->ConfigMagicNumber != OEMGetMagicNumber())

//{

// KITLOutputDebugString("ERROR: LoadBootCFG: ConfigMagicNumber not correct. Expected = 0x%x ; Actual = 0x%x.\r\n",

// OEMGetMagicNumber(), BootCfg- >ConfigMagicNumber);

// ResetDefaultBootCFG(BootCfg);

// }

Do anyone have idea?

Best Regards,

Sam Wong
