Why not just call alt_write_flash at this point? What is the advantage of the separate erase_block/write_block functions over the simple write function? I have tried to search for more information on this but have come up blank. I hope someone can explain ...
By the way, I can use the same code to open and control my epcs all correctly,(because I have not use the epcs as the boot loader flash?) Can you give me some advice about how to open my boot loader flash? Because the epcs flash is to slow to ...
alt_get_flash_info() also returns no errors, but incorrect information regarding the erase regions of the EPCQ flash.It is clear to me that a region on the EPCS128 deliversregion_size 0x1000000 (size of the entire flash)number_of_blocks 0x40 (...
The flash itself (probably) allows single word writes provided that they only change 1s to 0s. The other fubar is that the flash 'block' always contains the boot code - even if you don't need it. I also suspect that you can directly bit-bang the (EPCS) f...
The flash device I'm using is epcs128. After running signal tap, it seems that there is quite a big delay between each byte read. The amount of the delay does seem reasonable according to the read speed I'm experiencing. I wonder if it is possible to configure this delay in any way...
