Apparently > adding it back manually doesn't solve this problem. Any idea what's wrong? For am62ax, there should be several items changed with this v8 series in order for remoteproc to work with the TI default firmware: 1. memory carveouts were reduced to 15MB [0] & edge-ai memory carveouts are not included here 2. mcu_sram1 node removed [2] If you want to catch up on the general direction for this series, please refer to [3]. atm remoteproc can fail with the default FW, but we are trying to move away from that firmware and this is the first step in that direction.
