TMDS64GPEVM: Sbl, crypto and ethernet example working together error

Part Number: TMDS64GPEVM

Hi TI Experts

I'm working on a bootloader project on the TMDS64GPEVM development board.

The versions of CCS, SysConfig and mcu_plus_sdk I use are as follows:

CCS: 12.1.0

SDK: mcu_plus_sdk_am64x_08_05_00_24

SysConfig: 1.14.0

I first started by integrating the crypto_aes_ecb_256 project into the sbl_ospi_linux project. As a result, I can use both bootloader and crypto modules and thus I can easily do what I want to do.

Afterwards, I integrated the enet_cpsw_rawhttpserver ethernet project into this project, which ran smoothly. Even though I perform the encryption and ethernet operations in different situations (i.e. when the enet driver is opened, the sa2ul and crypto driver is not opened or vice versa) I get an error like the one below.

Enabling Clocks!
EnetUdma_openRxCh: 2086
EnetHostPortDma_open: 121
Cpsw_openInternal: 893
Cpsw_closeInternal: 984
Assertion @ Line: 984 in /home/gtbldadm/nightlybuilds/mcupsdk_internal/jenkins/mcu_plus_sdk_am64x_08_05_00_24/source/networking/enet/core/src/per/V1/cpsw.c: hCpsw->hRxRsvdFlow != NULL

When I run the enet_cpsw_raw http server example in mcu_plus_sdk alone, it works properly. I attribute this to udma. Because both crypto and enet modules use pktdma. When I activate pktdma in both modules in SysConfig, there is no problem. However, while it is running, the problem I mentioned above occurs.

Is this problem related to udma? If not, what could be the reason?

How can I use enet and crypto modules together?

Thanks...

Hi Ahmet,

Thanks for your query.

I will check on this and get back to you.

Hi Ahmet,

Thanks for follow-up. I am working on this.

Meanwhile, can you quickly try the same thing with latest release and update the results?

This is a single application having both ? or

Two different application running on 2 R5F cores and trying to access CPSW simultaneously ?

Thanks Ahmet for the confirmation.

Looks similar discussion on another thread

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1271176/tmds64evm-3-udma-instances-in-sbl-ospi-linux

So, I am assigning this thread to UDMA expert as well.

Hello Ahmet,

Actually, either BCDMA or PKTDMA with one instant can be used for different applications.

Let's say I have one PKTDMA Instant, but the same can be used for ADC and UART applications.

See below for configurations. ADC+ PKTDMA In this , channel type configured as RX mode and opened channel for ADC application and simailry, we

can open different channels for UART applications. The same logic can be applied to your use case. Use multiple channels with a single UDMA PKTDMA.

instant . When you configure PKTDMA from syscfg, it generates code for initializing PKTDMA instant, and next time you have to allocate different channels

for different peripherals.

/* Init channel parameters */
chType = UDMA_CH_TYPE_PDMA_RX;
UdmaChPrms_init(&chPrms, chType);
chPrms.peerChNum = APP_ADC_RX_PDMA_CH;
chPrms.fqRingPrms.ringMem = &gRxFqRingMem[0U];
chPrms.fqRingPrms.ringMemSize = UDMA_TEST_RING_MEM_SIZE;
chPrms.fqRingPrms.elemCnt = UDMA_TEST_RING_ENTRIES;

/* Open channel for block copy */
retVal = Udma_chOpen(drvHandle, rxChHandle, chType, &chPrms);
DebugP_assert(UDMA_SOK == retVal);

S.Anil.

So for my case, sysconfig generated the udma pktdma that will be used for crypto. Since pktdma will be used in Ethernet, should I add it as in the example you gave?

Actually, I know that each module activates UDMA with its own functions. For example, crypto opens the udma channel with the crypto_open() function and enet opens the udma channel with the enet_open() function.

I think the settings codes you shared belong to the udma_adc_read example. I think there is a different situation there.

Thanks

Yes . You should add it to either an Ethernet or crypto application and allocate different channels and UDM objects for two applications.

Actually, the same approach is used for your application as well. You can try my proposal, and please let me know if you face any problem.

The same approach is also shared in the link below.

Hi Swargam Anil

I noticed something while trying your advice.

Since ethernet udma was not working, you wanted me to configure ethernet udma as in the code snippet you shared above.

Swargam Anil said:
/* Init channel parameters */
chType = UDMA_CH_TYPE_PDMA_RX;
UdmaChPrms_init(&chPrms, chType);
chPrms.peerChNum = APP_ADC_RX_PDMA_CH;
chPrms.fqRingPrms.ringMem = &gRxFqRingMem[0U];
chPrms.fqRingPrms.ringMemSize = UDMA_TEST_RING_MEM_SIZE;
chPrms.fqRingPrms.elemCnt = UDMA_TEST_RING_ENTRIES;

/* Open channel for block copy */
retVal = Udma_chOpen(drvHandle, rxChHandle, chType, &chPrms);
DebugP_assert(UDMA_SOK == retVal);

But there is something missing.

In this example, UDMA_PDMA_CH_MAIN1_ADC0_CH0_RX is defined as APP_ADC_RX_PDMA_CH. However, for my usecase, there are no macros such as UDMA_PDMA_CH_MAIN1_ENET_CH0_RX or UDMA_PDMA_CH_MAIN1_CRYPTO_CH0_RX. That's why this advice didn't help me much.

Can you set up and try this scenario (sbl+ethernet+crypto) that I created?

Thanks...

Hello Ahmet,

Ya, sure, just point out which examples need to be integrated into a single project. So, I can do it and will share it with you.

Can you please point out which examples need to be taken from below , and similarly, you should point out the ethernet example as well?

C:\ti\mcu_plus_sdk_am64x_09_00_00_31\examples\security\crypto

I will integrate them from the sbl_ospi_linux project.

S.Anil.

Hello Ahmet,

Thanks for sharing details, and I can try to create a project by the on or before Friday and will update the status.
