Hi, Denny, The way system test verify edma working is through Crypto performance test which shows the edma interrupt (edma_ccint) increases after the test. The logs are shown below. The generic dmatest is not used and has been removed from top level build. I submitted a jira for it. cat /proc/interrupts CPU0 CPU1 17: 0 0 CBAR 32 Level gp_timer 18: 0 0 GIC-0 29 Level arch_timer 19: 841795 2172460 GIC-0 30 Level arch_timer 22: 0 0 CBAR 4 Level l3-dbg-irq 23: 0 0 WUGEN 10 Level l3-app-irq 25: 1 0 CBAR 232 Level dra7xx-pcie-main 26: 0 0 CBAR 233 Level dra7-pcie-msi 27: 1 0 CBAR 121 Level talert 29: 0 0 CBAR 8 Level omap-dma-engine 32: 1 0 CBAR 361 Level 43300000.edma_ccint 34: 0 0 CBAR 359 Level 43300000.edma_ccerrint root@am57xx-evm:/test# modprobe tcrypt mode=500 sec=1 [80169.707808] [80169.707808] testing speed of async ecb(aes) (ecb-aes-omap) encryption [80169.715773] test 0 (128 bit key, 16 byte blocks): 630707 operations in 1 seconds (10091312 bytes) [80170.722281] test 1 (128 bit key, 64 byte blocks): 331086 operations in 1 seconds (21189504 bytes) [80171.722252] test 2 (128 bit key, 256 byte blocks): 12278 operations in 1 seconds (3143168 bytes) [80172.722120] test 3 (128 bit key, 1024 byte blocks): 7571 operations in 1 seconds (7752704 bytes) [80173.722070] test 4 (128 bit key, 8192 byte blocks): 3628 operations in 1 seconds (29720576 bytes) [80174.722281] test 5 (192 bit key, 16 byte blocks): 598873 operations in 1 seconds (9581968 bytes) [80175.722155] test 6 (192 bit key, 64 byte blocks): 303737 operations in 1 seconds (19439168 bytes) [80176.722243] test 7 (192 bit key, 256 byte blocks): 14753 operations in 1 seconds (3776768 bytes) [80177.722106] test 8 (192 bit key, 1024 byte blocks): 7323 operations in 1 seconds (7498752 bytes) [80178.722058] test 9 (192 bit key, 8192 byte blocks): 2960 operations in 1 seconds (24248320 bytes) [80179.722328] test 10 (256 bit key, 16 byte blocks): 580537 operations in 1 seconds (9288592 bytes) [80180.722168] test 11 (256 bit key, 64 byte blocks): 279123 operations in 1 seconds (17863872 bytes) [80181.722241] test 12 (256 bit key, 256 byte blocks): 8371 operations in 1 seconds (2142976 bytes) [80182.721983] test 13 (256 bit key, 1024 byte blocks): 7175 operations in 1 seconds (7347200 bytes) [80183.721995] test 14 (256 bit key, 8192 byte blocks): 3253 operations in 1 seconds (26648576 bytes) [80184.722237] [80184.722237] testing speed of async ecb(aes) (ecb-aes-omap) decryption (more logs omitted) root@am57xx-evm:/test# cat /proc/interrupts CPU0 CPU1 17: 0 0 CBAR 32 Level gp_timer 18: 0 0 GIC-0 29 Level arch_timer 19: 847049 2178678 GIC-0 30 Level arch_timer 22: 0 0 CBAR 4 Level l3-dbg-irq 23: 0 0 WUGEN 10 Level l3-app-irq 25: 1 0 CBAR 232 Level dra7xx-pcie-main 26: 0 0 CBAR 233 Level dra7-pcie-msi 27: 1 0 CBAR 121 Level talert 29: 0 0 CBAR 8 Level omap-dma-engine 32: 437509 0 CBAR 361 Level 43300000.edma_ccint 34: 0 0 CBAR 359 Level 43300000.edma_ccerrint

Any suggestions for how to investigate the connection between the lcdc and the framebuffer (and why the data is not appearing on the lines) would be gratefully received. All the best, Richard

Hi Key, I'm trying to do the same things like you. Could you kindly share " usbdmscglue.c" which you modified for reference? Thanks a lot. BR, Rex

Hello James and Lali, Thanks for taking the time to try helping me out. I've finally found the issue with our design. We hadn't been able to mount the eMMC on Linux, and it would only appear under /dev if we lowered the speed below 10MHz. We identified that this was due to a signal integrity issue. We finally tracked this bug down to a HW design issue (not all lines had been pulled up properly - we thought they were). Anyways, after fixing the HW issue, my eMMC tests now run (under Starterware with the current "fixed" mmcsdlib files), and we can mount it under Linux at 52MHz. I did manage to run some tests from the RTOS SDK using CCS as well. All seems to be working properly. Thanks again! Cheers! Carlos

hi pavel, i have tried command line instructions from the Linux Core Audio User's Guide, but it is noisy. please provide the scripts what you have tested in the EVM

[quote user="satyanarayana P G64"]please provide the scripts what you have tested in the EVM[/quote] What is this script? Where you have found that AM572x EVM audio have been tested with script? Regards, Pavel

Hi Kemal, In that link, Add the Linux kernel configuration “CONFIG_FB_PRE_INIT_FB” to reuse the framebuffer contents that was set up by the U-Boot. but that option not able to enable it in TISDK Linux kernel version 4.4.32. Even we tried with changing display timing parameters in u-boot( with rasterDisplay), But still the errors occurred while insmod tilcdc driver in Linux kernel. After insmod of tilcdc module the tty service(minicom) gets inactive. above dmesg are taken from ssh Please help us solve the issues I tried this lists.freedesktop.org/.../104415.html patch to recover the sync lost error in Linux kernel version 4.4.32. But no improvement.

The rootfs on your board might be wiped. Can you reflash the SD card and retry?

I'm sorry for taking so long to reply, The Kernel is a fork of https://git.ti.com/ti-linux-kernel/ti-linux-kernel/commits/ti-lsk-linux-4.4.y starting at the merge of 4.4.67 from the linux kernel sources, therefore the name. I want to use the Userspace Remoteproc API to load the DSP Image from within my userspace software. I do not want to place a unencryptet DSP Image on the filesystem. Best regards, Olli

Hi Pavel, I mean script is command line instruction or software to test the audio input and output. my assumption is that it might used in EVM for clearing the tests before release for sale. regards satya

Satya, See if below wiki pages will be in help: processors.wiki.ti.com/.../LTP-DDT processors.wiki.ti.com/.../Sitara_PSP_Test_Setup Regards, Pavel

Hi ， in the beginning of kernel start, it succeed. then I read gpio1's SYS_STATUS, it is 0x1 now, I begin to reset gpio1 by sysconfig After I set gpio1‘s sysconfig by 0x1f，the gpio1’s sysstatus[0] turn to 0 ，and never turn to 1, at last show softreset failed (waited 10000 usec)

in the beginning of kernel start, gpio1 will reset，it's ok After kernel has started, read gpio1 sysstatus[0] ,it's 0x1 then I reset gpio1 by set gpio1 syssysconfig by val 0x1f , GPIO1 SYSSATUS[0] turn to 0 ,and never turn to 1, softreset failed (waited 1000usec) I use board tmdsevm572x ,am572x gpio1's init code is : static struct omap_hwmod dra7xx_gpio1_hwmod = { .name = "gpio1", .class = &dra7xx_gpio_hwmod_class, .clkdm_name = "wkupaon_clkdm", // the clk source is different from other gpio(2-8) .main_clk = "wkupaon_iclk_mux", .prcm = { .omap4 = { .clkctrl_offs = DRA7XX_CM_WKUPAON_GPIO1_CLKCTRL_OFFSET, .context_offs = DRA7XX_RM_WKUPAON_GPIO1_CONTEXT_OFFSET, .modulemode = MODULEMODE_HWCTRL, }, }, .opt_clks = gpio1_opt_clks, .opt_clks_cnt = ARRAY_SIZE(gpio1_opt_clks), .dev_attr = &gpio_dev_attr, };

Hi Guru, I test gpio1 software reset through the following command # ./devmem 0x4ae10010 /dev/mem opened. Memory mapped at address 0xb6f5f000.

HI Nikhil, We are using customized J6- DRA7xx board. We are trying to load the display DSS application ( bsp_examples_displayDss_m4vpss_release.xem4 image -vision-sdk ) via linux . We have attached the dts for the same. We are getting the below log messages. From the logs, only ipu2 image is loaded & up. But for the customized image ipu1, it is not loaded . What may be the problem ? how to debug ? calling omap_rproc_driver_init+0x0/0x24 [omap_remoteproc] @ 1116 [ 93.805765] omap-rproc 58820000.ipu: assigned reserved memory node ipu1_cma@9d000000 [ 93.818641] remoteproc0: 58820000.ipu is available [ 93.824547] remoteproc0: Note: remoteproc is still under development and considered experimental.

Hi, Denny, I tried with ProcSDK 3.3.0.6 (not the latest) on AM572x GP EVM. THe dmatest works. Please see logs below. The issue you encountered is because dma0chan0 is used. root@am57xx-evm:~# uname -a Linux am57xx-evm 4.4.41-gf9f6f0db2d #1 SMP PREEMPT Tue Jul 25 09:45:11 EDT 2017 armv7l GNU/Linux root@am57xx-evm:~# cat /sys/class/dma/dma0chan0/in_use 1 root@am57xx-evm:~# modprobe dmatest timeout=2000 iterations=1 run=1 [ 148.876330] dmatest: Started 1 threads using dma0chan4 [ 148.881853] dmatest: dma0chan4-copy0: summary 1 tests, 0 failures 177 iops 1242 KB/s (0) [ 148.891938] dmatest: Started 1 threads using dma0chan5 [ 148.892271] dmatest: dma0chan5-copy0: summary 1 tests, 0 failures 3367 iops 13468 KB/s (0) (more logs omitted) Please verify if this solved your issue.
