Part Number: TMDS64GPEVM
We have made custom am64x board based on Evm . In our custom board size of boot0 partition of EMMC is 2MB . We are able to flash first 2 bootloaders but we are not able to flash the uboot.img to boot0 partition of emmc due to size limitation .
is it possible to load uboot form user partition ?
Hi Paras,
In TI AM64x Linux SDK, tiboot3.bin, tispl.bin, and u-boot.img boot by default from the same boot media.
For eMMC, three binary are in eMMC boot area, which normally uses an underlying storage technology more reliable than the user area.
1. Boot area is raw partition, where binary load is at the fixed offset, for example,
- tiboot3.bin @sector 0 (R5 SPL, and loaded by bootrom)
- tispl.bin @sector 0x400 (A53 SPL, and loaded by R5 SPL)
- u-boot.img @sector 0x1400 (A53 u-boot, and loaded by A53 SPL)
The offsets are defined in "am64x_evm_r5_defconfig" for "tispl.bin", and "am64x_evm_a53_defconfig" for "u-boot.img"
One option would be optimizing the three binary size to see if it is feasible to fit all three into eMMC boot area.
2. If binary optimization not feasible, in theory, it is doable to load "u-boot.img" from user area.
A basic idea: in spl_mmc_load() in "$u-boot/common/spl/spl_mmc.c", when filename=="u-boot.img", re-direct to eMMC user area instead of eMMC boot area.
It would involve further code customization to bring EXT4/EXT3 FS support depending on eMMC user partition configured.

Hi Hong,
I just want to know if Falcon boot is possible as we don`t have any specific requirement for u-boot.
Hi Paras,
Falcon mode is not supported on K3 family of devices, i.e. AM64x.

Hi, hong ,
I have optimized the bootloaders (by disabling unused commands and drivers) now sizes of bootloaders are -> 421KB(tiboot3.bin) , 680KB(tispl.bin) and 868KB(u-boot.img) . I have flashed bootloaders to emmc boot-0 partition and linux is booting fine .
But now i can neither reset from the u-boot shell or reboot from bash shell . In boot case shell is stuck
Uboot-shell -> pb

Is there any dependency on uboot for doing soft reset ?
Have i disabled something specific from menuconfig of spl/u-boot which is responsible for soft reset/reboot ?
Please Note : if i use the bootloaders (un-touched /unmodified [using default defconfig] then reset form uboot-shell and reboot from bash shell is working .
Hi Paras,
"reset" cmd @u-boot is supported by u-boot DM driver "ti_sci_sysreset" in "u-boot/drivers/sysreset/sysreset-ti-sci.c"
It depends on "CONFIG_SYSRESET_TI_SCI".
There's similar kernel TI_SCI driver for "reboot" in Linux kernel.

i have created the diff file of .config file for default version of defconfig of spl/u-boot image and modified .
I have not disabled anything related to "SYSRESET_TI_SCI" either in uboot or in kernel.
Moreover same Kernel Image is used in both case. If i use the default defconfig for SPL/U-boot image then reset/reboot works.
This looks like a bug in uboot.
Hi Paras,
Can we run some test on your setup?
- add "#define DEBUG" on the very top in "u-boot/drivers/sysreset/sysreset-ti-sci.c"
- build u-boot
- run "reset" cmd @u-boot prompt
- any debug msg printout from "u-boot/drivers/sysreset/sysreset-ti-sci.c"?
Best,
-Hong
