Hi, I am new to the Omap1510 Innovator board. I am trying to put u-boot on the board. So please be patient in reading the following and answering for the same.
I am using the following hardware: 1. Omap1510 Innovator board 2. JTAG 3. Serial cable connected to COM1 on my PC
I am using the following softwares/tools: 1. Code Composer Studio 2(OMAP) 2. Spectrum Digital CCS Debug Tools for OMAP CCS 2.2x 3. VTI HOST for putting applications on board via JTAG 4. Windows XP's Hyperterminal Communications tool for reading things in memory using serial cable. 5. u-boot 1.1.1 sources from http://sourceforge.net/projects/u-boot 6. I have a prebuilt arm-softfloat-linux-gnu toolchain.
I am using the following steps to build the u-boot image (in Redhat Linux 9.0): 1. make distclean 2. make omap1510inn_config 3. vi cpu/arm925t/config.mk Here I have changed the line: PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ -mshort-load-bytes -msoft-float Replaced it with: PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ -msoft-float 4. vi Makefile Here I have removed the line (on line 124) : examples \ 5. vi board/omap1510inn/config.mk Here I have changed the line: TEXT_BASE = 0x11080000 Replaced it with: TEXT_BASE = 0x00000000 6. make CROSS_COMPILE=arm-softfloat-linux-gnu- ARCH=arm dep 7. make CROSS_COMPILE=arm-softfloat-linux-gnu- ARCH=arm all
These steps give me the u-boot.bin file. Then I used the following steps to convert u-boot.bin to u-boot.m0 (in Redhat Linux 9.0): 1.dd conv=swab if=u-boot.bin of=u-boot.swab 2.arm-softfloat-linux-gnu-objcopy -O srec -I binary --gap-fill=0xFF u-boot.swab u-boot.m0 3.objcopy -O srec --srec-forceS3 u-boot.m0 u-boot.m0
These steps give me the u-boot.m0 file. I had then put this file on the board as follows (in Windows XP): 1. The memory configuration switches were set on omap1510 Innovator board with S1 = ON and S2, S3, S4 as OFF. 2. Set the VTI HOST as follows: JTAG driver: sdgoarm9.dvr Board.dat file: ccBrd0.dat FLASH Copy function: SRAMFlashWriter.m0 Register : Program Counter set to 0x0 3. Downloaded the u-boot.m0 file using VTI HOST. 4. Switch off the power supply for board. 4. Changed the Memory Configuration switch settings to S1, S3 to ON and S2, S4 OFF. 5. Switch on the power supply for board. 6. Set the Hyperterminal (Start-->Programs-->Accessories-->Communications-->Hyperterminals) tool in Windows XP as follows: Connected to: COM1 BaudRate: 115200 Data Bits:8 Parity: None Stop Bits: 1 Flow Control: None
After all this was done the connection was established but nothing was visible (the u-boot prompt was not shown).
So please help me out to get u-boot on the board. If anybody has been succesful in porting u-boot on omap1510 innovator board please tell me how you have done so, starting from building u-boot to putting it on the board with the available hardware resources.
I desperately need help. So please reply soon.
