p2020 boot from sd card

weizhou — Sat, 02 Jan 2016 18:04:20 GMT

hi all:

My CPU is P2020,I want to boot from sd card,I use the P1020_P2020RDB_20101101_ltib software package,but no success,no message come from uart,I sure the communication between CPU and sd card is correct,the sd_clk,sd_cmd and sd_dat0 has wave from oscillograph，the flowing is my operation record:

1) Which Freescale's SDK is used?

2) Please provide the SDCARD U-Boot binary image for inspection.

3) Is debugger connection possibe during booting from SD card?

4) Is the board capable to boot from another source (NOR, NAND, SPI)?

In the log it is printed "part_type = 0x83" - this is incorrect.

Should be "part_type = 0x6" - because only FAT16 and FAT32 are supported.

Use 'fdisk' to to change the partition ID = 6

Thank you ,ufedor

My sdk is P1020_P2020RDB_20101101_ltib.

there is no any debugger connect to my board.

the board designed by I in scratch,not offical develop board.

I change part_type=6 use 'fdisk' ,but still no success,but I add address/value pairs in config_sram_p1022ds.dat that operates GPIO port 9 that connect a LED on my board,the LED can been turned on,but I can not turn off it in start.S.

the flowing is whole information:

[root@localhost u-boot-2009.11-cloud]# ./boot_format config_sram_p1022ds.dat u-boot.bin -sd /dev/sde

It is a little endian machine.

Re: p2020 boot from sd card

My board only can boot from sd

Re: p2020 boot from sd card

weizhou — Sun, 03 Jan 2016 17:30:23 GMT

I do not know that my u-boot whether has been executed,the code I added to control GPIO in start.S is the first instruction,flowing is :

.globl _start_e500

_start_e500:

	/let the status led turn off/
	lis	r1,GPIOBASE@h //0xff70f000
	lis	r0,GPIOVAL@h //0x00000000
	stw	r0,0(r1)
	stw	r0,+8(r1)

/* clear registers/arrays not reset by hardware */
	/* L1 */
	li	r0,2
	mtspr	L1CSR0,r0	/* invalidate d-cache */
	mtspr	L1CSR1,r0	/* invalidate i-cache */

	mfspr	r1,DBSR
	mtspr	DBSR,r1		/* Clear all valid bits */

so,I feel the u-boot is not executed at all.

Please consider to open a sevice case because this could be a complicated technical issue - refer to the How I could create a Service Request?

Please provide the SDCARD U-Boot binary image for inspection.

I do not know how provide my u-boot binary file ? !

hi ufedor:

this is my u-boot.bin binary file. I use flowing way to compile it:

make P2020RDB_SDCARD_config

make

Re: p2020 boot from sd card

ufedor — Mon, 04 Jan 2016 08:33:10 GMT

Please use attached pre-built SDCARD U-Boot image from the SDK 1.4.

If there will be no UART output, then the board has to be debugged.

Re: p2020 boot from sd card

weizhou — Mon, 04 Jan 2016 08:56:29 GMT

OK,thank you ufedor,I try it.

Re: p2020 boot from sd card

weizhou — Mon, 04 Jan 2016 12:01:54 GMT

hi ufedor:

I use pre-build sdcard u-boot image from the sdk 1.4,but no message come from uart,the flowing is my operation recorder:

./boot_format config_sram_p1022ds.dat u-boot-sd-P2020RDB-PC_SDCARD-git-r34.bin -sd /dev/sde

It is a little endian machine.
