Use caution when replying, = clicking links, or opening attachments. Hello, We have added support for the LS1021A in barebox (from v2022.03) At present= neither Linux and barebox are able to probe the PCIE device connected to P= E1 The board has a switch fabric connected to PCE1. Using U-boot we are able to see this device and the NXP bridge Using barebox we see only the Bridge. Then, it fails on the first read to g= et the header type from the deivice on bus 1. We know this driver works on the LS1046A as it can detects a PCI card on th= e LS1046A-RDB. Both the LS1021A (32-bit cpu) and LS1046 (64-bit cpu) have their PCIE space= to access the device conf, I/O and mem space in 64-bit address space On the LS1046 I do see access at 0x40.xxxx.xxxx while on the LS1021A, it is= only a 32-bit access using the lower 32-bit. As an experiemnt in U-boot, I have disabled the PCI driver and configured t= he bridge to access the device. To my surprise I could see the device not using the 40-bit address. So I am= not sure it gets mapped (I send a question to NXP) =3D> md 0x24000000 24000000: b86114e4 00100000 02000002 00000000 ..a.............
