The drivers layer implements the logical and communication protocols for any booting device in accordance with the interface specification. Finally the HAL implements the lowest level code for interacting with the hardware infrastructure IPs. End booting devices are attached to device IO pads. * * * * * * * AM335x starter kit HW user guider * AM335X : $5, 供电芯片 ：$4 * AM335X : $5, 供电芯片 ：$4 * * Am335x technical reference manual Am335x data sheet * * * * * * * * * * * * Am335x technical reference manual Am335x data sheet * OnTargetConnect() { GEL_MapOff(); GEL_MapReset(); GEL_MapAddStr(0 0, 0 R, 0); // Boot ROM GEL_MapAddStr(0 0, 0x0002C000, R, 0); // Boot ROM (also at 0x20000) GEL_MapAddStr(0x402F0400, 0, 0x0000FC00, R|W, 0); // SRAM Internal GEL_MapAddStr(0 0, 0 R|W, 0); // OCMC-RAM GEL_MapAddStr(0 0, 0 R|W, 0); // L3F CFG Regs GEL_MapAddStr(0 0, 0 R|W, 0); // L3S CFG Regs GEL_MapAddStr(0x44C00000, 0, 0 R|W, 0); // L4_WKUP GEL_MapAddStr(0 0, 0 R|W, 0); // McASP0 Data GEL_MapAddStr(0 0, 0 R|W, 0); // McASP1 Data GEL_MapAddStr(0 0, 0 R|W, 0); // USB0/1 GEL_MapAddStr(0 0, 0 R|W, 0); // MMCHS2 GEL_MapAddStr(0 0, 0 R|W, 0); // L4 PER GEL_MapAddStr(0 0, 0x00B00000, R|W, 0); // EDMA GEL_MapAddStr(0x4A000000, 0, 0 R|W, 0); // L4_FAST GEL_MapAddStr(0x4C000000, 0, 0 R|W, 0); // EMIF GEL_Ma
