Part Number: TMDX654GPEVM
We have this board rev.1 from Ti (www.ti.com/.../TMDX654GPEVM).
When we use Linux 4.19.94 PCIe is working. But not working CMA allocation.
But when we try to use Linux 4.5.74 and 2020 Arago CMA is working, but PCIe is not working.
What should we do for working CMA and PCIe ?
We downloaded the full sdk from here: software-dl.ti.com/.../Release_Specific_Release_Notes.html
Andrew,
Can you confirm by CMA you meant Continuous Memory Allocator, not the PCIe CMA?
If so, please further clarify:
1. What is connected to the PCIe slot?
2. how did you test CMA?
3. If you have a boot log, please send to me.
4. Please try to rename the "sysfw-am65x-evm.itb" to "sysfw.itb" on your boot media, as you will need to use the sysfw for SR1.0.
regards
jian
Yes I confirm.
1. What is connected to the PCIe slot?
To PCIe slot connected TMDX654GPEVM.
2. how did you test CMA?
I call
void ∗virt_addr = dma_alloc_coherent(my_dev, size_in_bytes, dma_addrp, GFP_KERNEL);
And this always return NULL for Linux 4.19.94. For linux 5.4 it return valid address, but PCIe is not working.
3. If you have a boot log, please send to me.
this is current boot log, arago 2020 (linux 5.4) with replaced sysfw.itb file

4. Please try to rename the "sysfw-am65x-evm.itb" to "sysfw.itb" on your boot media, as you will need to use the sysfw for SR1.0.
Yes, We tried it, but the same result.
Best regards, thx
Andrew,
since you have a board to board setup, can you confirm that the other EVM was using a different device tree where the PCIe is configured as EP, and EP board was brought up first, before RC was brought up. I assume you used the same steps as:
since you mentioned your previous build worked, but just to confirm. also can you confirm the SDK you used for the 5.4 kernel was 07_01_x?
regards
Jian
We use just one board. We are connecting a custom board to the pcie.
First of all, for this board we tried to use Linux 4.19.94, but func (dma_alloc_coherent) always return NULL.
After that we install linux 5.4 with 2020 Arago to the our board. Then func (dma_alloc_coherent) return valid value of address, but I can't saw PCIe device (FPGA with bitstream).
Andrew,
Sorry for the delayed response. I did not see the pcie were brought up in the linux log you sent earlier. Could you confirm which silicon revision you will be using for your final product? If using SR2.x, I suggest you use the SR2.0 IDK and latest SDK (7.03) for testing.
There are some power domain changes from SR1 to SR2.x, that should be comprehended by the system firmware. So if you need to test on SR1.0, I would use SDK 6.03.106 for all SR1.0 testing. Later SDKs defaults to SR2.x, you will need to make sure the sysfw are loaded correctly if you want to test on SR1.0.
regards
Jian
