Translation error at level1 in armv8 A72 cortex

Hi,

I am trying to enable MMU on LS1046ARDB using baremetal boot code . We are translating 1GB of DRAM as NORMAL READ WRITE memory . We are able to load entries into translation tables successfully . But as soon as MMU is enabled the execution is crashing and we are getting translation error at level 1 indicated in IFSC Field of ESR_EL3 Register.(Error code : 0x86000005)

Attached below is the assembly code we are using to set up Translation tables and enable MMU.

Are we missing anything? Any suggestions would be appreciated.

 

Thanks,

Faizanbaig Inamdar

 *      -ttb 0x80000000
 *      -el 3

 *
 * This memory map requires a total of 3 translation tables.
 * Each table occupies 4K of memory (0x1000 bytes).
 * The buffer pointed to by 0x80000000 must therefore be 3x 4K = 0x3000 bytes long.
 * It is the programmer's responsibility to guarantee this.
 *
 * The programmer must also ensure that the virtual memory region containing the
 * translation tables is itself marked as NORMAL in the memory map file.

  • If you've set TCR_EL1.T0SZ in such a way that your virtual address space is configured to be 512GB, then what you are describing is most likely the expected behaviour. As outlined in my earlier reply, doing this at 4KB granularity will cause translations to start at L1, in other words, the translation table pointed to by TTBR0_EL1 will be interpreted as an L1 table, rather than an L0 table. This means that the first entry in your L0 table is actually mapping only 1GB, not 512GB like you think it is, because the L0 table is being interpreted as an L1 table. If all other entries in the table are fault descriptors then you'll be getting a First Level Translation Fault.
