Hi folks, I was looking to activate the NPU on my beagley-AI chip, running armbian, and I couldn't find how. This chip as a NPU (AM67A) on the SOC from TexasInstruments (https://api.pageplace.de/preview/DT0400.9783895766572_A50990365/preview-9783895766572_A50990365.pdf). The loading of the NPU seems to have failed: mesg | grep remoteproc [ 8.461511] k3-dsp-rproc 7e000000.dsp: configured DSP for remoteproc mode [ 8.461728] remoteproc remoteproc0: 7e000000.dsp is available [ 8.461868] k3-dsp-rproc 7e000000.dsp: register pm nitifiers in remoteproc mode [ 8.464448] k3-dsp-rproc 7e200000.dsp: configured DSP for remoteproc mode [ 8.465124] remoteproc remoteproc0: Direct firmware load for j722s-c71_0-fw failed with error -2 [ 8.465164] remoteproc remoteproc0: powering up 7e000000.dsp [ 8.465271] remoteproc remoteproc0: Direct firmware load for j722s-c71_0-fw failed with error -2 [ 8.465285] remoteproc remoteproc0: request_firmware failed: -2 [ 8.480524] remoteproc remoteproc1: 7e200000.dsp is available [ 8.480658] k3-dsp-rproc 7e200000.dsp: register pm nitifiers in remoteproc mode [ 8.482329] remoteproc remoteproc1: Direct firmware load for j722s-c71_1-fw failed with error -2 [ 8.482375] remoteproc remoteproc1: powering up 7e200000.dsp [ 8.482488] remoteproc remoteproc1: Direct firmware load for j722s-c71_1-fw failed with error -2 [ 8.482501] remoteproc remoteproc1: request_firmware failed: -2 [ 8.964763] platform 79000000.r5f: configured R5F for remoteproc mode [ 9.047514] remoteproc remoteproc2: 79000000.r5f is available [ 9.048055] remoteproc remoteproc2: Direct firmware load for j722s-mcu-r5f0_0-fw failed with error -2 [ 9.048099] remoteproc remoteproc2: powering up 79000000.r5f [ 9.048222] remoteproc remoteproc2: Direct firmware load for j722s-mcu-r5f0_0-fw failed with error -2 [ 9.048241] remoteproc remoteproc2: request_firmware failed: -2 [ 9.234391] remoteproc remoteproc3: 78000000.r5f is available [ 9.234578] remoteproc remoteproc3: attaching to 78000000.r5f [ 9.402138] remoteproc remoteproc3: remote processor 78000000.r5f is now attached [ 9.505240] platform 78400000.r5f: configured R5F for remoteproc mode [ 9.547946] remoteproc remoteproc4: 78400000.r5f is available [ 9.548359] remoteproc remoteproc4: Direct firmware load for j722s-main-r5f0_0-fw failed with error -2 [ 9.548400] remoteproc remoteproc4: powering up 78400000.r5f [ 9.548505] remoteproc remoteproc4: Direct firmware load for j722s-main-r5f0_0-fw failed with error -2 [ 9.548521] remoteproc remoteproc4: request_firmware failed: -2 [ 15.281722] Modules linked in: algif_aead rpmsg_ctrl rpmsg_char cc33xx mac80211 libarc4 snd_soc_simple_card cc33xx_sdio snd_soc_simple_card_utils crct10dif_ce panel_simple pci_endpoint_test e5010_jpeg_enc cpufreq_dt pvrsrvkm(O) pwm_fan at24 rti_wdt cfg80211 ti_k3_r5_remoteproc btti_uart bluetooth snd_soc_davinci_mcasp snd_soc_ti_udma wave5 rpi_panel_attiny_regulator snd_soc_ti_edma snd_soc_hdmi_codec snd_soc_ti_sdma videobuf2_dma_contig v4l2_mem2mem videobuf2_memops videobuf2_v4l2 videobuf2_common snd_soc_core snd_pcm_dmaengine tc358762 snd_pcm videodev ti_k3_dsp_remoteproc ti_k3_common mc snd_timer snd omap_mailbox optee_rng efi_pstore nfnetlink [ 15.285991] Modules linked in: algif_aead rpmsg_ctrl rpmsg_char cc33xx mac80211 libarc4 snd_soc_simple_card cc33xx_sdio snd_soc_simple_card_utils crct10dif_ce panel_simple pci_endpoint_test e5010_jpeg_enc cpufreq_dt pvrsrvkm(O) pwm_fan at24 rti_wdt cfg80211 ti_k3_r5_remoteproc btti_uart bluetooth snd_soc_davinci_mcasp snd_soc_ti_udma wave5 rpi_panel_attiny_regulator snd_soc_ti_edma snd_soc_hdmi_codec snd_soc_ti_sdma videobuf2_dma_contig v4l2_mem2mem videobuf2_memops videobuf2_v4l2 videobuf2_common snd_soc_core snd_pcm_dmaengine tc358762 snd_pcm videodev ti_k3_dsp_remoteproc ti_k3_common mc snd_timer snd omap_mailbox optee_rng efi_pstore nfnetlink The usual lspci doesn't contain much: lspci 00:00.0 PCI bridge: Texas Instruments Device b010 How should I proceed to make it work?
