Cannot initialize a 2-D array of bytes from file directly (ram_init_file / $readmemh)

Conclusion:

initializing a 2 d array using a .mif file works for a 2d array:

Example:

// char mem
/*(* ram_init_file = "DE0_CV_SCREENCHAR.mif" *)*/ reg  charMem;
// color mem
(* ram_init_file = "DE0_CV_SCREENCOL.mif" *) reg  colMem;
// color mem
(* ram_init_file = "DE0_CV_SCREENPAL.mif" *) reg  palMem

I added the .mif files for these initializations.

initializing a 1 d array also works.

// helper variabeles to read .txt file:

reg [7:0] charMemTmp[2000];

reg [7:0] colMemTmp[2000];

reg [3:0] palMemTmp[48];

//--------------------------------------------------------
// initialize char memory (this statement will be synthetisised):
initial
begin
    $readmemh("DE0_CV_SCREENCHAR.txt",charMemTmp);
    $readmemh("DE0_CV_SCREENCOL.txt" ,colMemTmp);
    $readmemh("DE0_CV_SCREENPAL.txt" ,palMemTmp);   
end

In the zip file, all .mif and .txt are included. And also a .XLS with macro's to generate these files.
