Part Number: TMDSIDK574
Hello.
I have a custom board based on TMDSIDK574 (AM5749).
There is a problem that the u-boot is stopped while it is in progress. I am asking for help to solve this problem.
The circuit diagram and related materials are attached.

Symptoms of the current custom board
1. WARM RESET does not work normally.
- After inputting CPU RESETn in WARM RESET S/W, RESET OUT from CPU is normal.
- WARMRESETdp input of RESET OUT has been confirmed - PMIC RESSET_OUT does not work. (Condition is that BOOT1 is VRTC, Pullup, GPIO7 High) are all satisfied.
- PMIC VIO_IN 3.3 input has been confirmed, there is no 32KGO signal.
- 16.384MHz OSC Load Capacito has 27pF, but OSC is 18p. Unable to determine if it is normal 32KGO was checked, but there is no signal. (TMDSIDK574 also confirms no signal)
- An attempt was made to check the PMIC Power Good signal, but the location was not confirmed.
- When WARM RESET SW is pressed, RESETn operates in CPU, and this pin operates nRESETWARM of PMIC.
If BOOT1 is VRTC_OUT and GPIO 7 is VDD3.3, PMIC_RESET_OUTn should drop to Low, but it is not operating. (The operation was confirmed with TMDSIDK574.)
2. PMIC ON custom board booting without Power On button
3. Stopped during u-boot. The stopping point is changed according to the progress of time
- DDR Speed change (ddr_dpll_params_2664mhz -> 2128mhz) Probability increases until u-boot load progresses. Message output stopped
- u-boot last message
