hello,
I’m having some trouble when compiling uClinux for the Philips ARM LPC22xx Board!
What are the exact kernel settings I need to make in “make menuconfig” to make a correctly booting system when using the standard boot loader provide by Ulrich.
When I checked the “main.h” I saw:
//##########################################################################
#define KERNEL_START 0x81008000
#define BOOTIMG_ADDR 0x81100000
#define FILE1 "linux.bin"
#define FILE2 "romfs.img"
//##########################################################################
#define FOSC 12000000
#define PLL_M 4 // max. speed = 60 MHz
#define MSEL (PLL_M-1)
#define PSEL0 5
#define PSEL1 6
So I suppose I need the Crystal freq. = 12 Mhz and the CPU clock = 48 Mhz,
I made the following settings (as seen in the readme.txt file on the webste):
System Type--->
ARM System Type--->
[*] Philips LPC22xx
[*] Set flash/sdram size and base addr
(0x81000000) (S)DRAM Base Address
(0x00400000) (S)DRAM Size
(0x80000000) FLASH Base Address
(0x00200000) FLASH Size
LPC22xx options--->
[ ]Default Big Endian
(12000000) Oscillator Freqnecy
(48000000) ARM Core Frequency
[*] Remap Vectors to ram
General Setup--->
(root=/dev/ram0 initrd=0x81100000,800K console=ttyS0) Default kernel command string
When booting I see the boot loader, then all the dots which indicate the “linux.bin”-file being loaded but the I see something like this: “ Linux wird8 ‘üþ: Ð[/b] ” and it crashes…
What am I doing wrong?????
Many thanks in advance,
Polm

Hello,
I think I found a setting I forgot to make in "make menuconfig":
Character Devices--->
Serial Devices--->
[ ] 8250/16550 and compatible serial support
--- Non-8250 serial port support
[*] LPC2294 serial port support
[*] Support for console on LPC2294 serial port
Are these configurations correct?
When I do "make" I get a lot of errors like:
drivers/serial/serial_lpc2294.c: In function `lpc2294uart_int_rx':
drivers/serial/serial_lpc2294.c:103: warning: implicit declaration of function `clps_readl'
drivers/serial/serial_lpc2294.c:103: warning: implicit declaration of function `SYSFLG'
drivers/serial/serial_lpc2294.c:104: `SYSFLG_URXFE' undeclared
.........
What can I do about it?
P.S. I found a lot of serial.h files like in : /uClinux-dist/linux-2.6.x/include/asm/arch/serial.h and the do contain the following quarz speed setting:
" #define BASE_BAUD (10000000 / 16) "
but it's in comment so I think changing it will not change anything...
Can you please help me,
Thanks a lot in advance,

"make menuconfig" memory configuration
Hello, the "Serial Baud Rate"-problem is fixed but I still have some memory configuration troubles:
In the "make menuconfig" I'm not very sure about the following:
General Setup--->
(root=/dev/ram0 initrd=0x81100000,800K console=ttyS0) Default kernel command string
Is this correct? The size of the linux.bin file = 1 MB and the size of the romfs.img = 12 Kb.
When booting I reveive the following:
checking if image is initramfs...it isn't (ungzip failed); looks like an initrd
Bad page state at free_hot_cold_page (in process 'swapper', page 81202d28)

I thing the address 81200000 is better.
The Kernel has a size round about 1MB the beginning is 81008000 in this case the end is 81108000. Then you have trouble with the RAMFS image.

SD/MMC card driver
Dear Ulrich, thank you for all your help. I still have a problem:
I would like to mount the root filesystem to the sd/mmc card like you did on the kernel which came on the SD-card with the LPC-board:
Kernel command line: rw ext2 root=/dev/bd0p2 console=ttyS0
(as seen when booting your kernel)
But this doesn't work because I do not have a sd/mmc-card driver to enable in the "make menuconfig"..., I can't find any option related to mmc/sd...
Do I need to install some kind of patch or driver before compiling the kernel?
Many thanks in advance,
Polm

Copy the Driver in the current Directory! See README.TXT!!

Hello Ulrich,
I'm sorry but I don't understand exactly what you mean...
I tried replacing the mmc.c & mmc.h files in the ../linux-2.6.x/arch/armnommu/mach-lpc2294 folder by those in the "bootloader" folder on your CD-Rom but when I do "make" I receive errors like:
CC arch/armnommu/mach-lpc2294/mmc.o
arch/armnommu/mach-lpc2294/mmc.c:34: arch/philips/lpc2119.h: Onbekend bestand of map
make[2]: *** [arch/armnommu/mach-lpc2294/mmc.o] Fout 1
make[1]: *** [arch/armnommu/mach-lpc2294] Fout 2
make[1]: Leaving directory `/uc/uClinux-dist/linux-2.6.x'

Thanks for all your help,
Polm

Hello,
Sorry I gave the incorrect Driver!! Here the new one:
http://www.ulrichradig.de/site/arm_proj ... reiber.zip
The difference are in mmc.h therefore the driver can't found the MMC/SD card!
#define MMC_Chip_Select 10

Hello,
The sd/mmc driver is now working but I still have a problem when trying to mount the root filesystem. The startup output is the following:
MC/SD-Card Driver init OK
Using deadline io scheduler
Capacity 123 MB
bd0: unknown partition table
....
VFS: Cannot open root device "bd0p2" or bd0p2
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on bd0p2
How can I fix this problem? The /dev/mmc devices are correct and the sd card is diveded in 2 partitions as it should be:
Schijf /dev/sde: 125 MB, 125698048 bytes
4 koppen, 60 sectoren/spoor, 1022 cylinders
Eenheden = cylinders van 240 * 512 = 122880 bytes
Apparaat Boot Start Einde Blokken Id Systeem

/dev/sde2 83 1022 112800 83 Linux
Can you please help me?
