H3A module activating with SDRAM input

Julia K
Intellectual 280 points

Hi,
we work with VPFE of DM365 SOC and now I would like to get H3A working with still image saved in SDRAM. Is it possible to configure IPIPEIF/ISIF/VPSS registers to get this configuration working?

I tried this configuration but this doesn't work for me:


VPSS config:

....

CSL_VpssClkConfig clkCfg;

 memset(&clkCfg,0,sizeof(clkCfg));


 
clkCfg.ipipeifClkEnable = TRUE;
 
clkCfg.isifClkEnable = TRUE;
 
clkCfg.h3aClkEnable  = TRUE;
 
clkCfg.blClkEnable   = TRUE;

CSL_vpssSetClkConfig(&gCSL_vpssHndl,&clkCfg);

.....


IPIPEIF configuration:

status = CSL_ipipeifSetInputSource1(&gCSL_ipipeifHndl, CSL_IPIPEIF_INPUT_SOURCE_SDRAM_RAW);

m_Handle.ipipeifConfig.ipipeifClk.clkSel        = CSL_IPIPEIF_IPIPEIF_CLOCK_SELECT_SDRAM_DIV_CLK;


m_Handle.ipipeifConfig.ipipeifClk.clkDivM       = 1;
 
m_Handle.ipipeifConfig.ipipeifClk.clkDivN       = 1;
 
m_Handle.ipipeifConfig.ipipeifClk.pixelsPerLine = inWidth;
m_Handle.ipipeifConfig.ipipeifClk.linesPerFrame = inHeight;


m_Handle.ipipeifConfig.ipipeifDpcmConfig.enable        = FALSE;
m_Handle.ipipeifConfig.ipipeifDdrInConfig.enable          = TRUE;

 m_Handle.ipipeifConfig.ipipeifDdrInConfig.oneShotEnable   = TRUE;

m_Handle.ipipeifConfig.ipipeifDdrInConfig.rawDataShift    = 0; 
m_Handle.ipipeifConfig.ipipeifDdrInConfig.rawUnpackMode   = 0; 
m_Handle.ipipeifConfig.ipipeifDdrInConfig.inputAddr       = m_Handle.inVirtAddr;
 m_Handle.ipipeifConfig.ipipeifDdrInConfig.inputWidth      = inWidth; 
m_Handle.ipipeifConfig.ipipeifDdrInConfig.inputHeight     = inHeight;
 m_Handle.ipipeifConfig.ipipeifDdrInConfig.inputLineOffset = 0; 
m_Handle.ipipeifConfig.ipipeifDdrInConfig.dpcEnable       = FALSE;
m_Handle.ipipeifConfig.ipipeifDdrInConfig.dpcThreshold    = 0;
m_Handle.ipipeifConfig.ipipeifDdrInConfig.dpcmConfig      = &m_Handle.ipipeifConfig.ipipeifDpcmConfig;
 m_Handle.ipipeifConfig.ipipeifDdrInConfig.clkConfig       = &m_Handle.ipipeifConfig.ipipeifClk;

status = CSL_ipipeifSetSdramInConfig(&gCSL_ipipeifHndl, &m_Handle.ipipeifConfig.ipipeifDdrInConfig);

 

H3A module is configured and enabled and works fine when IPIPEIF input source is configured as parallel port.

As far as I can see from sprugu5a (from March 2010) it is possible to run H3A module while working with SDRAM image (5.11.1.1.3.1). Can you help with this use case?

 Thank you,

Julia
