Dear Sir or Madam,
I designed a circut board using AM3517, and set the SYS_BOOT[5:0] = 0b101101. Peripheral Booting Preferred Order should be USB->UART->MMC1->XIP(see sprugr0b.pdf page 2689). When I reset my board, the USB0_DM\USB0_DP, UART3_TX\UART3_RX, MMC1 pin, no signal appeared at all. It meant the ROM code didn't run or ran unnormally. So I could not boot my system via USB or UART3 or MMC1 etc.
Additionally, I test my board using AM35XX_BSL test code and download .out file via JTAG, the MMC1/SD and UART3 module is ok.
How can I check if the ROM code is running? Why it don't read image from peripheral or memory?
Thank you!
Viviwei
