ARM 11 is based on Powerful ARMv6 instruction set architecture. But I am not able to figure out if it has;


2-Sufficient RAM for porting Linux

Can someone enlighten me?


ARM11 is an architecture. It contains an MMU. The ARM architecture itself doesn't have any RAM at all, that is dependent on the Chip you use (for an example I will assume an i.MX31 which uses the ARM11 core) and the amount of RAM you can interface via its memory controller. I know that the i.MX31 supports 256 MB (maybe eben more). Therefore this should be enough for a Linux installation.

You won't port Linux by yourself to such a chip, as this will usually be done by the chip vendor (or some subsidiary). Freescale (the vendor of the i.MX31) provides a board support package for both Linux and Windows CE (see section Run-Time Software). Of course, you are free to make improvements or changes to that basic board support package.

  • \$\begingroup\$ you mean the SDRAM required by CPU for booting kernel is not an on-chip RAM? \$\endgroup\$ – gpuguy Dec 11 '13 at 9:41
  • \$\begingroup\$ Also why you said Linux porting is done by the chip vendor when linux kernel is freely available? \$\endgroup\$ – gpuguy Dec 11 '13 at 9:46
  • \$\begingroup\$ Yes, (DDR-)SDRAM is typically attached as an external chip via the on-chip memory controller (there are some exceptions but those are essentially chip-on-chip packages inside one single package); Linux porting is done by the chip vendor because this can be quite a lot of work - why would you want to do it on your own, if it's already available? \$\endgroup\$ – Tom L.
