In T2080 custom board, when cfg_rcw_src [0]_[1:4]_[5:8] Value 0_0100_0000 are set to SD CARD BOOT option.

Did power cycle: observations are:

  1. HRESET_B is not released by processor (Always low)
  2. Observed clock on SDHC_CLK pin which is connected to SD card (SD card is having image of RCW only). no clock on this line


But while emulator is connected and read the contents of POR Status Register 1 (DCFG_CCSR_PORSR1) from processor. the values shown proper.

Can someone please let me know how to debug this issue.
