Hello, Could you please sketch what your memory map looks like? What else is attached to the external port? JaaC --- "K.

See section 11.6.2.3 "Writing to BMS memory space" in System Desing chapter of the SHARC manual. You first set the BSO bit in SYSCON, then create the data you want to appear on the bus in memory, then fire the dma controller. The core can not write to the bms memory space, only dma can.

HI, I have AND with MS3 & BMS signal. still i am unable to program the flash. If i try to access MS3/ (0x300 0000) space, but i am not getting MS3/ chipselect. what could be the problem. I have programmed SYSCON = 0x20000, WAIT = 0x21a28401. Please give me the solution to solve these problem. Regards, K.Sankar, Sr-Hardware Design Engineer. Emuzed India Limited.

I bet it doesn't boot either. > If i try to access MS3/ (0x300 0000) space, but i am not getting MS3/ > chipselect. what could be the problem. > I have programmed SYSCON = 0x20000, WAIT = 0x21a28401. > Please give me the solution to solve these problem. Can you put an o'scope on ms3 and run a program like test: r0 = dm(0x3000000); jump test; That will tell you if your waits are correct too. MS3 should be firing at that address according to the manual. Patience, persistence, truth, Dr. mike |
