07:32 AM Software Development: RE: Write to SharedMem from DSP and read it from ARM: No you don't need ot use SetSharedMemCfg() or SetPoolCfg() if you are not using the tcDspInbound and tcDspOutbound me... Michael Williamson
03:57 AM Software Development: RE: Write to SharedMem from DSP and read it from ARM: Hi
do i need to use

09:18 AM Software Development: RE: Write to SharedMem from DSP and read it from ARM: DSP code is OK, though if you have the caches enabled for the regions of SRAM or RAM you may need to add a cache writ... Michael Williamson
09:05 AM Software Development: RE: Write to SharedMem from DSP and read it from ARM: Hi thanks for the quick reply. I found some stuff of how to do it on the ARM side, following the example you pointed ... stefan nielsen
07:33 AM Software Development: RE: Write to SharedMem from DSP and read it from ARM: The linux OS uses virtual memory addresses. You can't access RAM by physical address in the normal case.
You need... Michael Williamson
03:25 AM Software Development: Write to SharedMem from DSP and read it from ARM: Hi im trying to write to some shared memory from the DSP and read it back from the ARM. Ive expanded the HelloWorldDS... stefan nielsen

07:08 AM PCB Development: RE: MityARM-1808F SATA connection problem: What version of the kernel are you using? Michael Williamson

11:30 AM PCB Development: RE: MityARM-1808F SATA connection problem: From the kernel boot message, occasionally it failed to link to 3G speed, it linked up to 1.5G, but most of the time ... Jun Mo

07:24 AM PCB Development: RE: MityARM-1808F SATA connection problem: I am fairly certain that the lengths on the module for the SATA lines are matched. I will check with our PCB designe... Michael Williamson

10:36 PM PCB Development: RE: MityARM-1808F SATA connection problem: Thank you for your reply.
The HD is occacionally not attached. And the possibility of attahement depend on the brand... Jun Mo
10:13 AM PCB Development: RE: MityARM-1808F SATA connection problem: Hi Jun Mo,
For layout recommendations, be very careful with the SATA layout. Below are some guidelines to verify ... Adam Dziedzic
07:17 AM PCB Development: RE: MityARM-1808F SATA connection problem: Hi,
Is the HD not ever detected, or does it occasionally not attach?

03:04 AM Software Development: RE: Interrupt source code for DSP: I also got the SW to run. But I have to use the set_vector_enable() function. This function enables the gpio-input in... Stefan Krassin
01:20 AM Software Development: RE: Interrupt source code for DSP: Hi Stefan
i Have two FPGA GPIO cores one at 0x66000080(output) and one at 0x66000100(input). Anyway with some help... stefan nielsen

09:14 PM PCB Development: MityARM-1808F SATA connection problem: I use MitySOM-1808F to develop our data logging system which store data into a SATA2 SSD HD. We design the mother boa... Jun Mo
10:31 AM Software Development: RE: Interrupt source code for DSP: Are you sure that the baseaddress for the input gpio is 0x66000100? How long is your address vector from the EMIFA IF... Stefan Krassin

(Are you using the DSP/BIOS MityDSP-L138 Platform.tci file as a template for you BIOS? )
yes im using it, from... stefan nielsen
07:42 AM Software Development: RE: Interrupt source code for DSP: For the GPIO, you should only use SetISRCallback(). The tcDspFpgaGpio class will call the register_isr_callback() me... Michael Williamson
