SSP issue on LPC4088 Embedded Artists Dev Kits

Hi,

I configure SSP1 on LPC4088 dev kits using LPCOpen v1.03 to talk to TI ADC ADS8332 using SPI protocol. I can not get it to work. Here's couple information that we've seen so far. Both signals of Clock, MOSI from master (LPC4088) are good, however there is nothing from MISO, also chip select is low all the time. we also checked the documents and LPCopen code, there is a big discrepancy between LPCOpen and hardware configuration that on board schematic the SPI-SEL is GPIO69 and it's mapped to P2.14 however in Board_SSP_Init() function configures as P5.3.

Am I missing anything ?

Any input is very appreciated.

Thanks
LN

Hi, LN,
Please double check your pin configuration.
On EA 4088, SSP1 is P0.7, P0.6, P0.8 and P0.9 with LPCOpen V1.03 code. No signal is related with P2.14.
SSP2 is P5.2, P5.3, P5.1 and P5.0 with the LPCOpen V1.03 code.
Thanks,

Thanks LN. We will double check the LPC code and get back to you.
