LPSPI_DRV_MasterTransferBlocking gets TIMEOUT error

xu_wenming — Sat, 28 Mar 2020 02:05:50 GMT

Hello,

I'm using S32K148 with S32DS.ARM.2018.R1.

LPSPI_DRV_MasterTransferBlocking gets TIMEOUT error in some cases:

Configuration of LPSPI:

const lpspi_master_config_t spi0_ipc_sys_ma_MasterConfig0 = {
.bitsPerSec = 12000000U,
.whichPcs = LPSPI_PCS1,
.pcsPolarity = LPSPI_ACTIVE_LOW,
.isPcsContinuous = false,
.bitcount = 8U,
.lpspiSrcClk = 80000000U,
.clkPhase = LPSPI_CLOCK_PHASE_1ST_EDGE,
.clkPolarity = LPSPI_SCK_ACTIVE_LOW,
.lsbFirst = false,
.transferType = LPSPI_USING_DMA,
.rxDMAChannel = 0U,
.txDMAChannel = 1U,
.callback = NULL,
.callbackParam = NULL,
};

Testing cases:

1. LPSPI_DRV_MasterTransferBlocking(SPI0_IPC_SYS_MA, send_data, NULL, 16, 100);

>> OK.

2. LPSPI_DRV_MasterTransferBlocking(SPI0_IPC_SYS_MA, send_data, NULL, 32, 10000);

>> TIMEOUT. I have already set timeout to 10000 and even more, still timeout.

3. LPSPI_DRV_MasterTransferBlocking(SPI0_IPC_SYS_MA, send_data, receive_data, 32, 10000);

>> OK.

4. LPSPI_DRV_MasterTransferBlocking(SPI0_IPC_SYS_MA, send_data, receive_data, 32, 100);

>> OK. Less timeout still works.

5. LPSPI_DRV_MasterTransferBlocking(SPI0_IPC_SYS_MA, send_data, receive_data, 256, 100);

>> OK. More packets still work.

Hello,

Could you, please, update your SDK version to the newest 3.0.2 at first?

Hello Diana,

Thanks for your reply, I'll try to update my SDK to version 3.0.2.

I have made a lot of configuration using ProcessorExpert, before upgrading the version, could you please help me confirm that the new version is compatible with old version PE configuration?

Best regards,

Matthew Xu

Hello Diana,

Additional question is:

Which version is the latest stable version?

Best regards,

Hello Matthew,

All updates and IDE can be found here:

https://www.nxp.com/design/software/development-software/s32-design-studio-ide/s32-design-studio-for-arm:S32DS-ARM?&tab=Design_Tools_Tab

The latest SDK version for S32DS for ARM 2018.R1 is 3.0.2.

However, there is another version of S32DS for ARM 2.2. This version of IDE has integrated S32 SDK 3.0.2.

So, you can also consider the usage of the newest S32DS.

About compatibility, I'm afraid you might come across differences.
However, the RTM release of SDK is fully tested and ready to be released in the market and integrated into production.

Best regards,

Diana

Hello Diana,

Thanks for your information again. I'm gonna do it.

Consider it's kinda a big project to migrate all configurations to the new version of S32DS, it takes some time.

I'll share the test result on new version of SDK with you after upgrading.

Best regards,

Matthew Xu
