Hello,
I have a BRAM and DRAM blocks available on the FPGA side of the ZCU102 platform.
I would like to make them accessible for jailhouse cells. For instance, a BRAM
block is mapped to the 0xa0000000 address.
To do that, I inserted this address into the root and non-root cell
configurations as mem regions:
Non-root:
{
.phys_start = 0x00A0000000,
.virt_start = 0x00A0000000,
.size = 0x200000, //2MB
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE
},
Root:
{
.phys_start = 0x00A0000000,
.virt_start = 0x00A0000000,
.size = 0x200000, //2MB
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE | JAILHOUSE_MEM_EXECUTE,
},
When I run the non-root cell and try to write into the address:
int *bram_ptr = (int *) 0x00A0000000;
*bram_ptr = 10;
I got an unhandled data write at 0xa0000000. What am I missing here in the
configs?
Thanks
Giovani
