Hi Yoshihiro Shimoda, * Strategy 1: I add usb_cpu_init following your tutorial: int usb_cpu_init(void) { *STCBR3 = 0x18; *SRSTR = 0x18; cpu_wait_ms(50); *EXCPGCR = 0x21;//0x28; *PECR = 0x1500; cpu_wait_ms(50);

Re: [U-Boot] [T-Engine] UBoot configuration for T-Engine/SH7727 MS7727CP02 DevKit

Hi, thaoth. I think that your board cannot communicate with USB device at all. SH7727 has EXCPGCR register. Do you set this register? When I used this CPU before, I did the following setting. STCBR3 = 0x18; SRSTR = 0x18; wait_10msec(); EXCPGCR = 0x28; wait

Hi Nobuhiro Iwamatsu, 1. Clock frequency of board. #define CONFIG_SYS_CLK_FREQ #define TMU_CLK_DIVIDER 4 /* 4 (default), 16, 64, 256 or 1024 */ #define CFG_HZ (CONFIG_SYS_CLK_FREQ / TMU_CLK_DIVIDER) I don't understand how to set CONFIG_SYS_CLK_FREQ va
