we are working on a new board based on LS1012A SOC that includes secure boot feature. The TA_PROG_SFP PIN that enables secure boot has to be powered with 1.8V to burn internal fuses.
According to the LS1012A DS, "For all other operating conditions, TA_PROG_SFP must be tied to GND.". This create a manufacturing issue since we need to program the board and then, rework it with a 0ohm.
Here my questions:
1. Is it acceptable to tie TA_PROG_SFP to GND by a 100ohm resistor?
2. What would be the maximum resistor value?
Thank in advance for your support.
