After verification, 0x1FE & 0x1FF are still available for v3, v4 & v5. Use the FLASH? function from the YUPS module to find what type of board you have. Look at page 16 of the clupdate.pdf manual for board description. If you have a v3/v4 board type 0x2257 or a v5 board, you need to do the following 1) copy Flash:0x1F8..0x1FF sector to RAM:0x810..0x817 2) copy RAM:0x800 to RAM:0x816 3) copy RAM:0x804 to RAM:0x817 4) erase the Flash:0x1F8..0x1FF sector 5) copy RAM:0x810..0x817 to Flash:0x1F8..0x1FF If you have a v3/v4 board type 0x2256 then its simpler, you need to do the following 1) erase the Flash:0x1FE sector 2) copy RAM:0x800 to Flash:0x1FE 3) erase the Flash:0x1FF sector 4) copy RAM:0x804 to Flash:0x1FF Best regards, Sylvain PS: I have not forgotten to reply to your last email, just missing time. |
