Design Requirement Boot strap signals as mentioned in the Table 7-1, should not be driven by external devices until the module (SoC) comes out of reset. This mandates implementation of appropriate power sequencing mechanism on base-board. That is, there has to be 150ms delay between Supplying power to LS module (SoC) and power to any other device on the base-board. Table 7-1: Boot Strap Signal Requirement Typically 150 ms is the time taken to come out of the reset after power on of the module (SoC). Boot Strap Signal Description UART_TXD0 Can be driven logic low but should not be driven logic high. UART_TXD1 Can be driven logic high but should not be driven logic low. GPIO36 Can be driven logic high but should not be driven logic low. I2S_TXD Can be driven logic low but should not be driven logic high.
