Other Parts Discussed in Thread: DRA821
Tool/software:
Hello,
Now that me and my team are on the new SDK 9.02, we have picked back up the task of enabling in-line ECC on the DRA821.
We found some TI documentation outlining DDRSS ECC in U-Boot. In the documentation, it says to enable ECC by adding the ti.ecc-enable boolean property to the memory controller node. We built an image for both our custom hardware and the EVM with this hange, along with CONFIG_K3_INLINE_ECC=y enabled in the config file of U-Boot. With these changes, we cannot boot either our custom hardware or the EVM. For the EVM, we tried to boot via WKUP_UART, but we are getting stuck on tispl.bin. When it reaches tispl.bin, it freezes (I do not see a timeout error whatsoever).
We were linked to this E2E thread below and were asked to implement the changes from this E2E thread. We looked at the patch files from the E2E post. The patch is for an older version of u-boot. The files that we have are very different, and it looks like TI has already added most of the ecc patch. We will need additional support from TI to get ECC enabled on the DRA821.
Regards,
Lewis
