[AM335X WINCE7][BSP_WINCE_ARM_A8_02_30_00]How to write logo.nb0 into SLC flash

Hi,

It seems to be you can copy logo.bmp to your sd card so that the eboot is looking for the same on sd card.

Also in past I haven't seen any such method of downloading a logo file from Platform Builder.

Hi Tony,

have you solved this problem?

I'm running into the same problem.

Thx

Thomas

Has anyone managed to get the logo displayed from NAND?

My settings are

Main:
  Boot device:   NK from SDCard FILE
  Debug device:  Internal EMAC
  Retail Msgs:   disabled
  Device ID:     0
  Flashing NK.bin:   enabled
  OPP Mode:   MPU[500Mhz @ 1.10V]

 SDCard:
  Filename:      "logo.nb0"

But I also get

Init HW: controller RST
SDCARD: requested speed 1000000, actual speed 1000000
SDCARD: requested speed 25000000, actual speed 19200000
BLSDCardReadLogo:  cannot open Logo.bmp
OEMPreDownload: Filename logo.nb0

BL_IMAGE_TYPE_UNKNOWN

Terry,

Not sure if you are trying to show a logo from Eboot in NAND or on SD card.

You can include a bitmap image in Eboot itself by modifying the .bib file for Eboot, example:

FILES
; Name        Path                                 Memory     Type
; ----------- ------------------------------------ ---------  ----
  logo.bmp    $(_TARGETPLATROOT)\files\logo.bmp    EBOOTNAND  SHU

Note the 'U' flag which specifies to include an Uncompressed file.

To get a pointer to the bitmap data in Eboot you'll need to traverse the TOC:

extern "C" ROMHDR * volatile const pTOC;

// FindFile() - traverse ROM header to find file data (case sensitive!)
unsigned char *FindFile(const char *szFile)
{
    FILESentry *pFileSentry;
    unsigned int i;

    // File TOC follows module table which follows ROM Header
    pFileSentry = (FILESentry *)((UCHAR *)(pTOC) + sizeof(ROMHDR) + (pTOC->nummods * sizeof(TOCentry)));

    // Check filename of each entry
    for (i = 0; i < pTOC->numfiles; i++, pFileSentry++) {
        if ( !strcmp ((char *)pFileSentry->lpszFileName,szFile) ) {
            return ((UCHAR *)pFileSentry->ulLoadOffset);
        }
    }

    // File not found
    return NULL;
}

From your code you would do

unsigned char *pLogo = FindFile("logo.bmp");

From there it's just a matter of extracting the bitmap data and copying to the framebuffer. The BSP may already have routines to do this.

Best regards,
Carsten

Hi Carsten

Thanks for the info. I managed to sort of sort it out without having to implement any code.

I know how to boot from SD and get our company Logo to appear as the Splash Screen but our final product will have NAND only and no Ethernet so I need to get everything booting and working out of NAND.

I followed the instructions in http://processors.wiki.ti.com/index.php/WinCE-BSP_ARM-A8_User_Guide to flash XLDRNAND.bin, EBOOTND.bin and nk.bin. I managed to do this and could boot from NAND but there was absolutely nothing on the display during boot.

I found that the code for displaying the logo was not being included in the EBOOTND.bin because #define BUILDING_EBOOT_NAND was missing. Once this code was enabled the default 4 rectangles were displayed as the Splash Screen as it could find no logo.bmp.

The way I found to get the logo to show from NAND is to download AM33X-nand-logo.raw. This flashes XLDR, EBOOTND and logo.bmp. (see http://processors.wiki.ti.com/index.php/WinCE-BSP_ARM-A8_User_Guide#Flashing_the_board_.28AM335x.29_over_UART)

To get the nk.bin in, use the method described at http://processors.wiki.ti.com/index.php/WinCE-BSP_ARM-A8_User_Guide#Flashing_the_board_through_SD_card  for nk.bin only.

The logo.bmp is stored in C:\WINCE700\platform\CM_T335\FILES and needs to be changed as required.

Its not very elegant but it seems to work. If anyone has a better method please post
