CC2652P7-Chip support

[Bosemani]

Hai @Koenkk We designed a board having CC2652P7 chip and flashed CC1352P7_coordinator_20230507.zip Firmware. I tested Zigbee2mqtt It worked well.

But Firmware have maximum TX power 10 dBm. but, We need 20 dBm Tx power. I asked in TI form to build in 20 dBm for CC2652P7, Here is the solution Link

I build a code based on instruction like this link Also I make changes recommended by TI for 20 dBm.

I flashed and tested the code.

Now I'm getting this error

I'm using simplelink_cc13xx_cc26xx_sdk_7_10_01_24 Is patch is requird?

why we need to do this In Code Composer Studio, expand the 5 projects and for each open znp.syscfg, expand Power Management and change Minimal Poll Period (ms) to 1000, change it back to 100 immediately and save the file. ?

Any other configuration required?

I went through many Issues in github. But I haven't got any clarity on this.

Otherwise my patch doesn't apply, this saving make the structure of the znp.syscfg files consistent.

It looks that the firmware crashes somehow, but why I have no clue (I haven't investigated 20dbm with the CC2652P7 yet)

Hai @Koenkk I tested compiled firmware with the TI Z-Tool. It's working without any crash.

Is patch is required to apply? I haven't applied, I'm using latest version of sdk.

Hai @Koenkk For your reference I sniffed the Serial communication & here is the result. TX_ZIGBEE2MQTT - Command from Zigbee2MQTT RSP_OF_CC2652P7 - Response from CC2652P7

In this these 2 commands TX_ZIGBEE2MQTT : FE022113000F3F RSP_OF_CC2652P7 : FE026113000070

TX_ZIGBEE2MQTT : FE022113210011 RSP_OF_CC2652P7 : FE026113000070

By referring in Z-stack Monitor pdf _SYS_OSAL_NVLENGTH Description This command is used by the tester to get the length of an item in non-volatile memory. A returned length of zero indicates that the NV item does not exist.

From this i get to know, Zigbee2mqtt is reading some nvs flash from cc2652p7, But that doesn't exist In the chip.

This causes Error in zigbee2mqtt.

Is patch is required to apply? I haven't applied, I'm using latest version of sdk.

Yes please try with the patch applied

[Bosemani]

Hai @Koenkk After applying patch. Its working fine! Thank you

[BrotherDen]

Hi @Bosemani could You please share your fiemware for CC2652P7 chip?

[skrue]

I'd also be interested in the 20dBm-enabled firmware for the CC2652P7 @Bosemani

[Bosemani]

Hai @skrue @BrotherDen I don't have that firmware with me. I just evaluated the chip functions & tested zigbee2mqtt. But anyway, you can compile firmware in code composer studio using the simple link SDK. Make sure In sys config of the project, Tx power is set to 20dbm.
