Tool/software: Code Composer Studio
When using the Gel file provided at https://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_DDR3_Init, I get the following error:
CortexA8: Trouble Writing Memory Block at 0x4c000010 on Page 0 of Length 0x4: (Error -2130 @ 0x4C000010) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.2.0.00002)
I have found that this error occurs on the last line of the following (lines 2139-2141 in the gel file):
WR_MEM_32(EMIF4_0_SDRAM_REF_CTRL, 0x0000613B); // Initially a large refresh period
WR_MEM_32(EMIF4_0_SDRAM_REF_CTRL, 0x1000613B); // Trigger initialization
WR_MEM_32(EMIF4_0_SDRAM_REF_CTRL, (0x10000000|SDREF)); // Move to a smaller more correct one
If I don't use the initial large refresh period, and instead write SDREF and then 0x10000000 | SDREF to the register, the gel file is able to load, but then DDR3_SlaveRatio_ByteWiseSearch_TI816x.out gets stuck after entering the ratio values. The frequency I am using is 796.5 MHz.
