Part Number: AM3356
Hi,
Let me talk about GPMC for AM335x.
GPMC timing is described in Datasheet and TRM like this.
But This is waveform of our target board.
ADV/ALE signal become low second time(Yellow circuit).
Could you tell me why it become Low ?
AAD Mux mode may become this waveform, But This case is AD Mux mode.
and I do not see this signal for AD Mux mode in TRM.
We set GPMC register like this:
HWREG(0x50000090) = 0x00000200; //GPMC_CONFIG1_1
HWREG(0x50000094) = 0x001E1E00; //GPMC_CONFIG2_1
HWREG(0x50000098) = 0x00030301; //GPMC_CONFIG3_1
HWREG(0x5000009C) = 0x1C0D1C05; //GPMC_CONFIG4_1
HWREG(0x500000A0) = 0x00181F1F; //GPMC_CONFIG5_1
HWREG(0x500000A4) = 0x0D070580; //GPMC_CONFIG6_1
HWREG(0x500000A8) = 0x00000F50; //GPMC_CONFIG7_1
Best Regards
