Re: Data Store Error when EDAC enabled

Section 6.2 applies also to the SDRAM. When the EDAC is enabled, a store byte (or half-word) will generate a read cycle first, then insert the stored byte, and

Data Store Error when EDAC enabled

We get an tt = 0x2B, data store error on our GR712RC when using SDRAM with EDAC enabled and we would like to understand better what causes this kind of trap as

Re: light FlashLED with gpio have error"unknown watchpoint hit"

Hello, Well for ml510 design some bits of gpio are reserved i.e gpio(0) is reserved for DSU break so you cannot write a '0' to this bit else it will generate

Re: please help Post Synthesis Simulation of Leon3

thanks for the guidelines. My simulation shows X all the time, no 0 or 1. I am using the attached script to synthesize leon3mp in Design Compiler. 1. is there

Re: please help Post Synthesis Simulation of Leon3

I don't know if there is a better solution, but I did gate level simulation and I can suggest at least 2 easy checks: 1. Add some printf() in the test program

Re: APB Bus limited to 16 slaves?

Never mind, I found the problem: I was unable to find it in the Linux source code, because it is not there. The info that Linux needs to discover devices are

Re: APB Bus limited to 16 slaves?

Thank you both for the advice. That would be a great solution if I hadn't changed already quite a bit the system interconnect. I'm only keeping the bus

Re: APB Bus limited to 16 slaves?

Hi, You can add a second AHB2APB bridge to have an additional 16 peripherals. e.g ... apb0 : apbctrl generic map (hindex => 1, haddr => 16#800#) port map

Re: APB Bus limited to 16 slaves?

A very simple solution would be to instantiate two AHB/APB bridges in your system. The you would not have to modify hardware or software (the kernel will scan

APB Bus limited to 16 slaves?

I tried to connect more than 16 slaves to the APB bus and I noticed that apbctrl.vhd is hardcoding 16 as maximum number of slaves. In particular, the signal
