An Error of booting up to DSP

[hoaho]

Dear all,

I am trying to boot an file named PHY.bin into the B4860 board. But the console window displays as:

are there anyone who know about the error HW SEM ?... Please give me a way to solve the problem!

Many thanks for your support!

Hello Hoa Ho,

It may be waiting for other DSP cores to go up.

If this is multicore project, please change in os_config.h:

#define DP_SINGLE_CORE                     ON

#define  OS_MAX_NUM_OF_CORES      1

Have a great day,
Lunmin

Hi Lunmin,

I also faced similar issue, I resolved it by doing following:

Just comment the function call   "osWaitForAllCores " getting called in b4860HetBootInitialize(), and you should be good to go for loading single core binary.

b4860HetBootInitialize-> Reference:

..\StarCore_Support\SmartDSP\source\arch\starcore\b4860_family/b486x.c

However I do get following issues in loading multicore image

1) When I load multicore dsp image :

(SIX CORES Configured and OS_Mulitcore=1, and also the OSwaitforallcores function disabled in het boot function)
1) dsp_bt -h 1 -c 0 -i c0.bin -c 1 -i c1.bin... -c 5 -i c5.bin -s shared.bin

but it still shows the same problem "waiting for hw  semaphore".

Any ways how to solve this problem for multicore??

2) I could run IPC integration example in smart dsp demo directory through power pc ,(IT IS A SINGLE CORE EXAMPLE)

I tried to convert it into multicore by making changes in os_config.h :

i) #define OS_NUM_OF_CORES                     OS_SOC_MAX_NUM_OF_CORES (i.e "6")

ii) OS_Mulitcore=1,

and also the OSwaitforallcores function disabled in het boot function.

Now the problem is the binaries getting generated are of unequal sizes:

core0.bin ->   200 kb

core1.bin->   15 kb

core2.bin->   15 kb

core3.bin->   15 kb

core4.bin->   15 kb

core5.bin->   15 kb

When i try to load this images , I get the same problem "waiting for hw  semaphore".

Binaries were generated using:

b4860_bin_creator.exe -cw '${SC_TOOLS_HOME}' -dir '${CW_Project}/ipc_integration_demo' -arch b4860 separate_shared_bin_files On

Any answers to this questions ??

regards
