Other Parts Discussed in Thread: SYSCONFIG
Hi,
I am trying to boot a custom board with an AM5726 SoC.
I'm told the design of the board has influences from the IDK, however the PMIC is not directly connected to the AM5726, as it has other roles on this board, and is managed by a separate uC.
There are two 4Gb 1866MHz memory chips and one 1Gb ECC, we since realise with errata i922 that ECC won't be realised with the AM572x, so I have removed this from the EMIF configuration.
I am using upstream U-Boot (2023.10), and upstream Linux (6.1.46).
What I think I have done correct so far:
* a complete sysconfig/pinmux config, and have generated using the scripts the padconf and iodelay content.
* a complete EMIF and correct EMIF configuration
* I think the DTS files are workable for both U-Boot and Linux, but they are not finished.
* console on uart3 is working
* booting to u-boot secondary boot loader and then to u-boot third boot loader from SD card. (SD Card is working)
But I only get so far if I disable the recalibrate_iodelay in board.c (i'll circle back to this later).
in uboot I can test the memory, most of it passes the test.
lmb_dump_all: memory.cnt = 0x1 / max = 0x10 memory[0] [0x80000000-0xbfffffff], 0x40000000 bytes flags: 0 reserved.cnt = 0x2 / max = 0x10 reserved[0] [0xbcf29000-0xbfffffff], 0x030d7000 bytes flags: 0 reserved[1] [0xbdf29b98-0xbfffffff], 0x020d6468 bytes flags: 0
=> ddr test 0x80000000 0xbd000000 Please wait ... ddr memory test PASSED! => ddr test 0x80000000 0xbe000000 Please wait ...
This last test hangs.

I realise having read many posts here prior to posting this that using the PMIC is strongly encouraged, and there are of course lots of reasons to use one. But for this particular "solution", the board designer believes we can forgo dynamic use of a PMIC, and instead the PMIC can be statically configured to provide the neccessary outputs. But if there is something we have over looked, well that is why I make this deviation from IDK clear.
It can be seen in the boot output, that I have not yet fully removed all PMIC code from the boot process either.
does this relate to why the board is not booting?
there are errors such as:
ti-sysc: probe of 4882c000.target-module failed with error -16 ti-sysc: probe of 4882e000.target-module failed with error -16 ... ti-sysc: probe of 48838074.target-module failed with error -16 ... ti-sysc: probe of 5600fe00.target-module failed with error -16
which correlates with a timer15, timer16, no-idea and a clock, possibly GPU related (for which AM5726 has none), but I think these wouldn't prevent the boot?
[ 1.324737] Unhandled fault: imprecise external abort (0x1406) at 0x00000000 [ 1.327819] Unable to handle kernel paging request at virtual address f880350c
which happens whilst sysc_probe is taking place:
[ 1.378997] PC is at sysc_probe+0xdd4/0x149c
IODelay.
The IODelay process appears to lock the boot up process. in CCS i see it is stuck in a nop loop. By process of elimination, I found that the first line of code that causes this failure is this: (dra7xx_iodelay.c)
static int calibrate_iodelay(u32 base)
{
...
reg = readl(base + CFG_REG_2_OFFSET);
...
}
However, with IODelay calibration disabled, I can read that register manually in U-Boot:
