Hello, Based on AN-4329, I assembled a test project (attached) for the FRDM-K64F which attempts to copy a function to RAM and run it, but I am getting a fault when attempting to call the function. The Source and Destiny variables seem to be in the correct ranges in copyToMyRam, but the call fails. AN4329 - NXP Note changes in the…(Show moreShow less)
Hi Make sure that you are creating a thumb-comform copy of the code in SRAM since if it i not correctly aligned it will fail. Below is an example where fnFlashRoutine() is a small subroutine to be copied to SRAM and later executed by calling fnRAM_code() Regards Mark …
Here is the code that I am using to put my MK36L256VLL4 chip into Deep Sleep but the system is drawing 175m volts. Hope some one can tell me where I am going wrong:
Hello Ping, Let me try this again. The code that I inherited worked fine, when in Deep Sleep the current was in the 4-20 micro amps. I have added 3 gpio lines that are being used now. I added them using Processor Expert and then I added the pins to the Shut Down function and the Start Up function, to turn them off and on. After adding…
Dear Forumers! I've started writing a communication stack, under FRDM-K64F board. Currently I'am trying to complete the initialization sequence of the ENET peripheral. So at this point what I'am want to do is to exchange data between my onboard Micrel PHY chip and my controller. To do this I've done the followings: MDIO init sequence:…(Show moreShow less)
Hi If the MII clock is higher than you want you can change the value in MSCR to reduce it. The following is the formula: MSCR = (((ETHERNET_CONTROLLER_CLOCK/(2 * MII_MANAGEMENT_CLOCK_SPEED)) + 1) << 1); But limit MSCR to 0x7e if needed. The MII doesn't have anything to do with the Ethernet operation (sending and receiving frames) so if…
Hello Everyone, I am using K60DN512 device with Lan8720A phy device. I have initialized the Ethernet MAC, but there is no data on MDIO pin (I have checked on logic analyser) I have done following initialization. GPIO SIM ->SCGC5 |= SIM_SCGC5_PORTA_MASK | SIM_SCGC5_PORTB_MASK; //Configure RMII0_RXER (PTA5) PORTA ->PCR[5] =…(Show moreShow less)
Hi I have same issue, done all clock register configuration correctly but I'm unable to get the clock of less than or equal to 2.5Mhz. On MDC pin I'm getting around 4.1 Mhz. And able to read raw packets on wire-shark! getting some random packets/frames. Please help me out Thank you Trilok
I've tracked my issues with K22f to board being stuck in hard fault handler: eg the bubble demo bubble.c: buble.c:140 BOARD_BootClockRUN clock_config.c:131 CLOCK_SetSimConfig(&g_defaultClockConfigRun.simConfig); fsl_clock.c:520 CLOCK_SetEr32kClock(config->er32kSrc); fsl_clock.c:663 SIM->SOPT1 = ((SIM->SOPT1 & ~SIM_SOPT1_OSC32KSEL_MASK) |…(Show moreShow less)
Hi, apologies for not giving more background. I have the K22f board and it used to work just fine. One day it just stopped (I was playing with PWM and servo control, it seemed to work fine, but next day I've tried to use it it wouln't work). I thought it's flashing issue, because the debug seem not to work, but after some massaging and more…
Hi, I use the K22 MCU, configured the clock to 80MHz. For configuring the clock I used USBDM default setup code. Now, I want to check if the clock is configured right: void FTM_EPWM(void){…(Show moreShow less)
Dear Jeremy, first thanks for your support. I use the Freedom Board K22 (512Kb) here. I verfied the internal clock to 80Mhz using the following function. void clkout_init(void){…
Hi , I am programming a custom board based on MK60DN512 chip. We are using LAN8720A as a PHY device. Tricky part is determing /setting the PHY ID. I don't know what is the default ID. In the datasheet they have mentioned that the we have to assert RXER pin low to set the PHY ID. How to assert RXER pin low when it is not configure as GPIO. …(Show moreShow less)
Hi, I'm using the Kinetis K60 towerboard (PK60DN512Z) and codewarrior 10.5. I am running the i2c example code, which prints out the accelerometer measurements. I would like to convert that to floating point value. Does anybody know how? Thanks.
Hi emWin 应该可以支持 KL26产品，不过没有对应的例程。可以联系Segger，看看他们是否有基于Kinetis的应用。 Wish it helps.
