C6657 direct SPI-NOR boot

Hello Rajasekaran,

Thank you for your information. I was able to download the file by accessing your direct link. How do I get to a web site which links the file? (not direct link)

The direct SPI-NOR boot is working fine. I can see that the program counter halts by IDLE instruction at 0x80000800 when I connect CCS without GEL. However it does not boot when I remake "spirom_le_swap.dat" based on default "spiboot.out". (not rebuild "spiboot.out"). The difference between default dat file and remaked dat file is only one byte. I seem that the difference is come from "nysh.spi.map". Should I change this file for C6657? Please give me some advice.

<default dat file>
1651 1 10000 1 37b
0x00005000
0x00003200
0x02002040
0x18000100
0x00000400
0x00000000
0x0000e803
0x0000f401
0x00000004
0x00000000

<remaked dat file>
1651 1 10000 1 37b
0x00005000
0x00003200
0x02002040
0x18000100
0x00000400
0x00000000
0x0000e803
0x5100f401
0x00000004
0x00000000

Hello Rajasekaran,

Thank you for your reply. I only changed "spiboot.bat" for the IBL_UTIL path and the copy command.

<spiboot.bat>
set IBL_UTIL=C:\ti\mcsdk_2_01_02_06\tools\boot_loader\ibl\src\util
hex6x spiboot.rmd
b2i2c spiboot.btbl spiboot.btbl.i2c
%IBL_UTIL%\btoccs\b2ccs spiboot.btbl.i2c spiboot.i2c.ccs
%IBL_UTIL%\romparse\romparse nysh.spi.map
copy i2crom.ccs spirom_le.dat
byteswapccs i2crom.ccs spirom_le_swap.dat
%IBL_UTIL%\btoccs\ccs2bin   i2crom.ccs     spirom_le.bin
%IBL_UTIL%\btoccs\ccs2bin -swap i2crom.ccs spirom_le.swap.bin

I also added a following system environment variable for invoking hex6x.
C:\ti\ccsv5\tools\compiler\c6000_7.4.4\bin

Then I type a command below.
D:WORK\SPIboot_ddr>spiboot.bat

I found that the default and the remaked "spirom_le.dat" have same data. (not spirom_le_swap.dat). There is 0x51 there.

Hello Rajasekaran,

I checked the "spirom_le_swap.dat".

0x5100f401 -> 0x0051=81 | 0x01f4=500
0x00000004 -> 0x0000 | 0x0400=1024

- 500: The bus_freq_khz is configured by "nysh.spi.map". This is corresponding to the "Bus Freq, kHz" of "SPI Boot Mode Parameter Table" in C6678 Data manual, isn't it?
- 81: Is this corresponding to the "Read Addr MSW"?
- 1024: Is this corresponding to the "Read Addr LSW"?

I seem this msw address parameter is not appropriate. How do I configure these address parameter? Please give me some advice.

Kazu
