9. IPL2 and eMMC boot
|
||||||
|
|
||||||
|
IPL2 is the 2nd boot loader based on NuttX and can be built as follows.
|
||||||
|
|
||||||
|
$ make distclean
|
||||||
|
$ ./tools/configure.sh lc823450-xgevk/ipl2
|
||||||
|
$ make V=1
|
||||||
|
$ MakeIPL2 ./nuttx.bin 0 2 0 0 0
|
||||||
|
$ cp LC8234xx_17S_start_data.boot_bin /tmp/
|
||||||
|
|
||||||
|
To write the IPL2 (LC8234xx_17S_start_data.boot_bin),
|
||||||
|
firstly build USB configuration image.
|
||||||
|
|
||||||
|
$ make distclean
|
||||||
|
$ ./tools/configure.sh lc823450-xgevk/usb
|
||||||
|
$ make V=1
|
||||||
|
|
||||||
|
Load the nuttx.bin with openocd + gdb
|
||||||
|
|
||||||
|
$ cd openocd-nuttx
|
||||||
|
$ ./bootstrap
|
||||||
|
$ ./configure
|
||||||
|
$ make
|
||||||
|
$ sudo ./src/openocd -s ./tcl -f ./tcl/board/lc823450_xgevk.cfg -c init -c "reset halt"
|
||||||
|
|
||||||
|
$ arm-none-eabi-gdb
|
||||||
|
(gdb) target extended-remote :3333
|
||||||
|
(gdb) load ./nuttx
|
||||||
|
(gdb) symbol-file ./nuttx
|
||||||
|
(gdb) c
|
||||||
|
|
||||||
|
Start USB MSC to copy nuttx.bin and the IPL2 to the FAT32 partition (/dev/mtdblock0p10)
|
||||||
|
then dd the files to the kernel partition (/dev/mtdblock0p4) and the IPL2 partition
|
||||||
|
(/dev/mtdblock0p1) respectively.
|
||||||
|
|
||||||
|
nsh> mkfatfs -F 32 /dev/mtdblock0p10
|
||||||
|
nsh> msconn
|
||||||
