PRUSS uio driver with omapl137 doesn't work

Other Parts Discussed in Thread: DA8XX, OMAPL138

Hi all,

I have question about pruss uio driver on OMAPL137 platform. I try to enable this driver with Linux kernel Community Linux PSP (Linux v3.3)
. What I did is:
- modification of drivers/uio/Kconfig to make visible pruss_uio with DA830
- da830.c -  .sram_dma = DA8XX_ARM_RAM_BASE, .sram_len = SZ_8K, added to davinci_soc_info_da830
- pruss resources registered



What I get from pruss_uio driver is error with memory allocation:

Could not allocate SRAM pool

What I have to add/modify to anable proper sram memory allocation ?  

With 2.6.37 I was able to use pruss_uio driver without problems. 

Regards Grzegorz
