Linux ARM (IMX6U) bare metal main frequency and clock configuration-EEWORLD

Collect

chmod 777 imxdownload //Give imxdownload executable permissions, just once

./imxdownload clk.bin /dev/sdd //burn to SD card

After the programming is successful, insert the SD card into the SD card slot of the development board, and then reset the development board. The effect of this test is actually the same as the test "7_key", but the flashing frequency of the LED light is faster than that of the test "7_key". Because the main frequency of the test "7_key" is 396MHz, and the main frequency of this test is configured to 528MHz, the code execution speed will be faster, so the operation of the delay function will be faster.

Nikkei: Arm China's leadership change has hidden dangers

Recently, the leadership change at British design company Arm and its subsidiary Arm China has caused a stir in the industry. The Nikkei Asian Review believes that the seeds of the dispute between the two sides can be said to have been sown two years ago. At that time, Arm, the world's leading intellectual property pr

ARM exceptions and interrupts

1 SWI interrupt processing steps: 1) When entering an interrupt, pc- lr, cpsr- spsr, and cpsr_mode are set to privileged mode, all of which are completed by hardware. 2) Registering the interrupt vector table is done by software. You can use the B instruction or the ldr and dcd tables to place a jump instruction at th

ARM embedded system serial port expansion

ARM embedded systems often encounter the need for multiple serial ports, but the number of native UARTs in ARM chip systems is limited, so it is necessary to expand more interfaces through other high-speed buses. This article uses Toradex 's Apalis i.MX6D/Q ARM computer module based on NXP i.MX6D/6Q processor to expand
