Hi, I am using ADSP21369 and I am able to write and read from SDRAM (MT48LC4M32B2 128MB). I have few questions and will be grateful if anyone could help 1) My SDRAM is connect to bank 0. At the moment I am giving the SDRAM start and SDRAM size as #define SDRAM_START 0x00200000// start address of SDRAM #define SDRAM_SIZE 0x00100000// size of SDRAM in 32-bit words.(i.e. 1M x 32) I...

Please refer to the chapter-10 of ADSP-21065L User Manual. The minimum size supported for SDRAM is 16 MBytes. If you use any size less than 16 MBytes (as you seem to be currently asking), you will not be able to use some of the address ranges of SDRAM - because these address ranges will be aliased to some other address ranges. For example with 8MByte SDRAM (as you are asking), (1) remaining ...

Hi, How can i know if my program is using the external memory (SDRAM)? How do I Enable it? I went to: project--> project options--> Link--> Processor-> Memory Usage-> checked the: internal SRAM and External SDRAM. It didn't seem to work.. then I noticed i can modify this too --> project--> project options--> LDF Settings--> External Memory-> checked the: Use external memory (SDRAM

Hi All, This is a question for anyone with BF53x experience. I'm using a BF533 ez-kit to test my code. I'd like to make a binary file that contains code that will execute in place in flash, copy code that will run in SDRAM and then jump to SDRAM and continue running code from SDRAM. The binary file will not use the on-chip boot loader. I'm having problems including the code which runs in...

Hi group, does anybody have experience using a two processor cluster of 21065L Rev. 0.2 with shared SDRAM? I have a feeling that because of its host of SDRAM bugs in the Anomaly List, a shared SDRAM setup using Rev. 0.2 doesn't work. Can anybody confirm or

I've problem with SDRAM write in parallel with SDRAM MDMA transfer - MDMA transfer invokes DMA error. Is that an anomalie or is something wrong with me? I've tried many combinations of relating registers without succes. I need to start urgent MDMA transfer but I need to be able to continue in main program in parallel with MDMA transfer. Main program should write to SDRAM in that time. Can you...

I have a small piece of code which writes data into sdram memory in a loop. I always reinitialize the CYCLES as zero before this operation and then right after the write loop, I store the CYCLES value into memory. If the data buffer which I am accessing is in L1 memory, it gives the same CYCLE value for every re-build and re-run, but its never consistent for SDRAM. Working on EZ-KIT....

hi Iam trying to interface TS201 with 16 bit external memory peripheral. in TS201 Ezkit they explained for SDRAM and EPROM interfacing. for EPROM they connected from A0-A18 address lines and D0-D7 data bus directly. and for SDRAM they configured A1 through A31 of TS201 and D0-D31 and D32-D63 data bus connected to SDRAM. so for 16bit data bus(D0-D15) and 12bit address(A0-A11) c...
